Hi Laura thanks for your reply. We're using tommee tippee bottles having their normal ones with the little valve in the teat for air release and also the 'anti colic' ones with the purple tube down the middle, but haven't found any difference using the anti colic one. I did buy a dr brown bottle at about 4 months but she didn't take to it well and didn't want to suck on it so didn't use it. She's on size 3 teat (I only found out about about 4 months that I was supposed to change the size so hopefully I'm on the correct one now).
She's always been a windy baby and is much better than she was but as she'll be 7months old on the 1st I thought that the wind would have settled down by now. It only troubles her at night and I think only really bothered following her night feed which at the moment is around 3am. I keep her upright for a good 20-30minutes after the feed and do my best to get a burp up- sometimes successful sometimes not, but even if I do get a burp they are not as good as the day time ones. Do you think it's normal to have wind like this at near 7 months, no one else's babies seem to have it when I ask. I feel like I'm missing something and if I did this one thing it would help her.
