Those bottles you bought - not the ones at £5 a bottle? I bought 2 and found them useless

MW said her feeding (which was 1oz) may not be down to colic but we automatically assume so. I moved her to teat 2's (prefer avent at this stage on teat 2) and she takes around 2oz - 2halfoz a feed ~ MW is happy with that! She explained to me the size of her little belly so try not to panic.
Caitlin also has moments of none stop crying (or it seems) I ended up in tears and feeling so frustrated like you the other night I sat & cried with her. She also pushes bottle away but an hour of hair pulling she will take a lil bit (what I call a top up tbh).
What medicine is it your using? When did you start? We use infacol & we were also told not to give up on it because it doesn't instantly make a quick fix

Colic or not it can help with her wind.
Hope this helps ~ Learning with you x
