3 weeks old and still not feeding more than 50ml

[Freyfreysmum]

As post title says, dd2 is feeding literally every 45 mins, and unhappy afterwards although will Not take the bottle.
She was 10 1/2lb when born and is 11 1/2 now so the weight gain is great, and hence why my GP and 2 HVs have told me to ride it out.
DD2 literally screams after a feed, 1oz on average, she takes in loads of air (yes Ive tried lots of bottles inc Dr Browns) and I dont know what to do. We've seen a cranial osteopath who was sure dd2 was tongue tied hence the tension that she found in various muscles etc across her neck and back, but Ive had 2 specialists, 2 paediatricians, and one GP look at her and all confirmed there is no doubt that she is not tt.
She has infacol, and we've tried colief, but still, Nothing is settling her. She only sleeps when she has got so hysterical that she cant stay awake. What do I do?

not much advice sorry but that sounds so hard

could it be reflux?

sorry, only other advice is to post this in the feeding section as you might get more advice
from someone who actually knows what they're talking about rather than just is sympathetic
