Lily (7mths) has a 6oz bottle twice a day which she usually finishes in about 3mins flat. We use the TT Closer to Nature bottles (am still bf twice a day too) with size 3 teats.

I only had two bottles and two teats at first but have just bought another couple because I'm not very good at keeping up with the washing up Since I've done this, though, whenever she has a bottle the teat seems to sort of suck into itself and the nipple disappears inside.

Am I doing something wrong, has Lily started doing something strange, or have I bought a dodgy pair of teats?! Trouble is, I've no idea which are the new teats and which are the old as they're all identical. Anyone else had this?

I have noticed mine sometimes do this too! I have noticed that it only happens when Ella is sucking really hard as she is mega hungry! I think it is because they are softer so move more easily if that makes sense?!

This happens with us too! think its when hes sucking hard also. I try and gently pull the bottle against his suck to try and prevent it. It always happens on the first part of the feed!

We had this with Nate when he was sucking too hard - we changed to Variflo teats and it doesn't happen any more!

found this on tt website:
Why is the teat collapsing when my baby is feeding?
The teats are made from silicone and due to the nature of the material it can knit back together. Open the valve by pinching it between your finger and thumb. This allows the air to flow through the bottle and prevent the teat collapsing.

Also your baby may want more milk than they are able to get. Try either a variflow teat or the next stage teat.

Thanks all! Good to know I'm not the only one this happens to and thanks for copying & pasting that, Girlinleeds. Will try variflow. Nearly got those to start with, HOW much more money can I give TT?

Hello lovely
I have 2 variflow TT teats you are welcome to have. I can post em or bring em when we meet next!
Little T has only used them once or twice so they are as good as new

Ah that would be great! No need to post them, she seems to get the milk fine, it just makes a bit of a mess. Next time we meet would be fine - thanks Joo!
