I'm wondering if anyone has, or has a link to, something which shows the comparison of a mw's tape measure - centremetres compared to "weeks"? -------------  |

Don;t know if it helps but it is on the back of the tape measure. I have in my notes from my last appointment measuring 30 weeks and the cm measurement is 27.5cm. Which is bang on for my dates, that does surprise me a bit. ------------- I was a puree feeder, forward facing, cot sleeping, pram pushing kind of Mum... and my kids survived! |

Not sure of the measure but i felt you were bigger than me at last shot becks but it is hard to tell when your trying to look at yourself i was 30cm for 30weeks 3 days, but that meassurement is your vaginal area rather than bubs so i supose its the placenta ??? but im no expert thats what i was thinking anyways

The cms usually correspond to the amount of weeks you are.
So as Vix said... 30cms at 30.3 weeks is spot on. I was measuring small for dates based on fundal height and midwife got a bit worried so she sent me in for a scan. Hannah was freaking huge!!! I don't know where the heck in hell she was hiding because I'm a bit on the small side... but a 9lb 6oz baby measuring small enough to warrant a growth scan?! Weird. Anyway, so while I say the measurments correspond to weeks - take that with a grain of salt.

Yea Nikki I had similar thing with Briona. Sent off for a growth scan in the last month and then she was born full-term at 8lb 4oz LOL. But there are two measurements. One is cm's and the other is slightly more generous. So at 33 weeks I was measuring 32.5 weeks but 29cm. Today I have measured 37weeks but that's only 33cm.
I had a different mw for the other two kids and she only measured cm's. I was trying to do a comparison chart for myself but am a bit stuck on converting the few weeks ahead of me... like how many cm = 38 weeks on the measure? Becks I might just have to "borrow" my mw's measure next time  I couldn't find anything on the net! Oh and I measured the same as you now, at my 29w2d appointment. ------------- |

| Oh I get ya... yeah I had two midwives who measured different... I thought they just started from a different measuring point rather than using different units...? |

| I think in the NZ pregnancy book there is a chart thing there too. but as others have said dont rely on it. I was measuring right on for my dates but Kobe was 6 weeks early and the size of a full term baby! |

I think most mw's take it with a pinch of salt, it's more for checking that bubbas are actually growing from week to week without having to pay for so many scans.
I feel like I'm carrying so much bigger this time - certainly I'm in a new size of clothes - but my fundal height seems to be much the same as with the other two - in fact closer to Hannah's who was 7lb 3oz than Briona's who was 8lb 4oz. For some reason Hannah's measurements were bigger  and that's with the same mw!------------- |

My midwife kept telling me I was probably having a big baby as she felt that I was 'big', however when I had checkups at the hospital, they weren't concerned and my extra scans showed a 'normal' size baby. Amelia was 8lb 4oz, born right smack on her due date. ------------- Selina http://lilypie.com">
