DD2 is 2 weeks tomorrow she is currently on cow & gate formula, she struggles getting more than 1-5-2oz in her at a time as we think she suffers with wind/ pains in her tummy. She really tenses up & thrashes about when she gets to a certain point on the bottle & struggles to take anymore. She can go anywhere between 2.5-4 hours between feeding try waking to give her a feed but sometimes she just isnt interested. It comes across as she wants more but just isn't able to as she is in pain. We are using infacol & the TT anti colic bottles which doesn't seem to be helping much.
Had the health visitor out today who was absolutely useless & didn't give us any advice at all. Told us to go the gp?? 
So I was wondering do you think we should consider changing her formula or just sticking it out until (hopefully) she grows out of it this wind?
