for all you mums out there. is there any correllation between baby size and due date? my dates are definitly right but my baby is weighing 28 weeks although his development etc is 30 weeks. will this increase my chances of having him late? i can only take a limited time off uni so if there is a chance im going to be late id rather stick it out as long as possible so i can spend more time at home afterwards. at this stage they reckon bubs will be round 6-7lbs but could quite possible be smaller -------------

I don't think size makes a difference, you can always go 2 weeks either side. I was over due and got induced because my gigantic bubba wouldn't engage her gigantic head into my pelvis 
I had a friend with a small bubba and she had her 3 weeks early. -------------

Yeah I don't think that it is related. If your babe is developementally at 30 weeks and you are sure of your dates then I'd go by that not the size. Sounds like you may just be going to have a small babe. ------------- http://lilypie.com">

hmmm maybe i will still leave at 40 weeks then. i was being really closely monitored by a speacialist when i was TTC so my dates are spot on but i was only 5lbs and DH was 7lbs. what is it that makes baby decide to come out at 40 weeks (or there abouts) is it a chemical/hormone thing? i know its off topic im just curious. lol -------------

I don't think the size matters too much because I've heard of people who have said that on a scan it said bubs was x big but it was out by quite a bit.. plus there's lots of growing time to be had yet.
Daniel measured as "fairly small" but came at 39wks and 7lb 12oz. My MW said I was made to have babies because I have wide hips and a wide pelvis and a strangely positioned pubic bone which doesn't much get in the way as some does which let him engage well and truely or something like that but I don't know that I believe that. I think I was just lucky and hoping for lucky again this time, it was wicked not going overdue lol |

Arianne was also measuring 2 weeks under, but she came at 39 weeks 6lb 15oz, she was just a small bubba and her development was perfect.
If you feel bubba is at 30 weeks then he most likely is. ------------- http://lilypie.com">

I think nobody truely knows the answer to that one, as in whether baby decides and starts labour or if mum's body decides enough is enough. It would be some hormone that kicks things off and keeps labour going though, just whether the hormone is from mum or bub is yet to be decided... -------------

From what my midwife explained to me labor is triggered when the baby's head (or feet) starts bumping the cervix. This action cause the body to produce the chemical/hormones that start the contractions. If you have been looking after yourself then I don't think you need to worry too much about your baby's size. Isobelle was small for dates as well and I had to go for 3 extra scans to make sure she was growing alright. At one stage she was measuring 3 weeks smaller than her gestation. She arrived at 38.5 weeks weighing 6lbs.5oz and healthy. |

Here's something slightly different for you & it definitely goes along the vein that you can't really predict it.
I was SFD going by FH which at 34 weeks I was measuring 31-32 weeks so got a growth scan bang on 34 week baby. At 38 weeks I was measuring 34 weeks FH again, baby was scanned & was normal for 38 weeks. 39 weeks was measuring 35 weeks & I had my baby that day, came out 6lb 11oz. The first growth scan predicted at 40 weeks a 7lb baby so I was still bang on really. We were exact on our dates as well. According to me I felt still weeks away from delivery but I delivered 1 week early. If you were a little baby the chances are you'll have little babies, size seems to run in families, well mine anyway. Maybe leave a week early just so you can get things sorted that you haven't done by that stage? ------------- Kel http://lilypie.com">

Oh, also scans can be rather out with size... I was told I was having an 8lb baby and she was 9lb 4oz. -------------

My first was 2 weeks early and 9lb1oz and the gremlins were huge for 36 weekers so all thru with lil miss I was expecting a huge baby. I had a growth scan at 36 weeks which put her around the 50th% (the others were all 97th for gestational age) and she was born bang on the 50th % at 39 weeks 7lb12oz so way smaller than I expected. There doesn't seem to be any rhyme or reason for it, random. -------------  Maya Grace (28/02/03)

ditto to this. At 34 weeks they predicted Aoife was 1.8kgs When she was born the following week she was 1.6kgs. |

I don't think there's any rhyme or reason either. Baby will come when they're ready. Mine came at 39+2 and she was only 6lb10. On a side note if you're feeling well enough to keep going there's no reason to stop uni early. I was only taking minimal leave last time too and so I went on ML the friday before I was due (I was due on a Wednesday). As it turned out I worked right up until the day I gave birth (I left work early that day because I was in the early stages of labour and I had her at 8:04pm). I am still pleased that I didn't have any extra time off and that every day of my maternity leave was spent with my baby. -------------

Firstly, I wouldn't panic in the slightest as it's normal for babies to be measuring up to 4 weeks +/- their gestational age. Once they get over that threshold is when they worry. Jack was 5 weeks behind from 27 weeks and I had fortnightly scans to check progress but if it had been any less behind they wouldn't have cared.
Baby weight doesn't determine labour. Their size is a mixture of the environment (your womb, placenta activity etc), nutrition (whether you smoke etc), and maternal and paternal birth weights. Apparently there's a formula that puts your height, you and your partners birth weights and previous children's birth weights (although we can't put Jack's in as he was IUGR) and it will give you an estimate. But generally its an average of the parents give or take the environmental impacts etc. As far as I'm aware they put 40 weeks as the gestation because that's at the point where the placenta is still working at optimum level. They go to 42 usually because things like baby implanting late or you still having a good placenta is fine. So generally if there's no room left and baby is not being nourished as much as they want, they realise there's something better on the outside and start moving to the white light lol |

sweet all good. im only at uni for 1 hour a day and the week im due DH is going to start taking the car to work so if im one of the unlucky that has their waters break and go into full blown labour ill make it to the hosp. otherwise im thinking im just gonna stay until i get the extreme tired/mucas plug/nausea/runs etc that is quite common in the days/hours before labour starts. i can only take a couple of weeks of so i wanna push the limit as stay as long as physically possible -------------

Hayden measured a good 2 weeks ahead up to about 38 weeks and then it started slowing down and by 40weeks he was spot on (spot on was 10lbs) but then I ended up being induced at 16days over due as he was engaged and I was 3cm dialated but nothing was happening and he ended up arriving by E C-Section on the 17th day overdue and was 9lbs 13oz.
No rhyme or reason and it will do your head in to try and predict it!!!!! If you are happy to keep going to Uni then do so up to the point where it feels too much physically and/or emotionally, you may not have waters break/lose mucus plug/get the runs etc. -------------

As a side note does anyone know if birth weight is hereditry. The reason why i ask is i was 6lb my brother 6.5lb my first cousins who is a girl bubes were both about 6lb too. Laos i think that my other cousin boy (brother and sister) his 2 girls were smallish too one was early though due to complications. Lurker out |

yea apparently but it is based of fathers weight. my OB worked it out based on mine and DH's birthweight when he saw my baby was quite little week after week but someone else said it was based on dad so im not sure which is right. lifestyle factors play a big part too though. smoking, eating habits etc.. -------------

When we thought DD was a 'whopping' 8lb from her scan we saw the specialist as I am/was quite small and mw was worried I couldn't have an 8lb-er naturally. The Specialist took one look at DH and said "next time choose a smaller fella" lol.
My sis and I were about 7lb each. DH was 8lb-something but he was 3 weeks early. I blame him for my giant baby anyway. -------------

| I don't know if birth weight is heredity but it make sense that there would be some connection. I was a small baby and am still small but DH is tall and was a big baby. However, I am the odd one out in my family the rest of my siblings were big babies.Both my babies weighed 6lb5oz at birth, Dominic was early though and was predicted to be over 8lbs if he went full term. |
