I've got 5 month old twins, born 8 weeks early so for many things they're measured against corrected age of 3 months.
My daughter has been a really good feeder but just recently has started feeding very poorly. She's on 6 feeds a day to total around 950mls. At the start of the feed she seems enthusiastic, but generally pulls away after about 100mls and then it's very, very difficult or impossible to get her to take more. She still readily accepts the bottle in her mouth, but makes her tongue flat or floppy and won't suck. She also seems easily distracted and will turn her head away to look at something else.
Has anyone got any bright ideas what could be the cause of this, or techniques to help? She had a cold 10 days ago but didn't seem particularly ill with it. She has been on formula only since about 12 weeks of age, we haven't changed the milk or the bottles - have just increased teat size to no 3 in the hopes that faster flow will allow more in before she refuses, in case sucking was tiring her out.
Her brother, in contrast, finishes his bottle almost every time and is very straightforward. I can't help comparing them and worrying that she'll fall behind and lose weight if she keeps this up. Any help gratefully received!
