Avent bottle feeding 4mths +

We have always used the Avent bottles and teats etc following the different sized flow teats or using the variable flow ones. I just looked on their website as I just realised we've been using the 3mths one for a while now (I'm such a bad mum! ) so I wanted to know where I could get the 4mths+ teats from. Avent says that the next stage is the sipper (no more teats).

Caitlin has been getting a bit fussy with her bottle over the past week or so (so I'm wondering if the milk isn't coming fast enough for her now), but I don't think she is ready for a sipper - or maybe she is?!?! What are the signs? or is it just an age thing?

Thanks

she's on the slit variable flow but it only has 3 lines on it (and if it remember correctly, the box said "to 3mths") on it.

Pur make the wide neck medium flow (3-6 months) ones Toni and I believe they fit the wide neck advent bottles just fine. You can buy them at Woolworths.

have they changed the teats james was on the no1 teats for ages till he was 6 months i would have put him on a sipper the mikl wold of gone everywere i have no2 and no3 teats toni all perloved but clean if you want them give me a pm

Ok, have done some research on the net and one of their websites says that the 3 hole one (medium flow) is suitable up to six months, and I have a bunch of those if you want them and haven't already got them. It says that the four hole teats are from six months up, but I can't remember ever having seen them around, and also the "three line" position on the 'one slot / variable flow' teat is apparently equivalent to the four hole one, but I never used those much because as I mentioned we switched types of bottle.

Here's the link I was reading if you want to check it out for yourself anyway: http://www.avent.com/uk/en/bottlefeeding_silicone_teats_indepth.php

I think we used the 3 hole one until Matthew was about 6 months, then went to the 4 hole one. They have them either at foodtown or farmers.

Thanks for the info ladies!
I think we might get a 4 hole one just to give it a go. We discovered last night that Miss Caitlin would like to be walked around whilst she is having her feed! Well laa dee daa! heheh

Alex will have the first half of his bottle no problem. Then have a wee break and then we have to sing while he finishes it. His favourite songs are Jingle Bells and Twinkle Twinkle.
