Thanks for replying.
No we haven't tried a sippy cup.
Water she likes, and gripe water. She's not dehydrated, lots of very wet nappies and the doc checked her fontanelle yesterday.
She stops sucking and plays with the bottle as if it's a dummy when she's had enough. She wriggles a lot and she sometimes pulls a 'yuk' face.
We have lots of breaks, and burps.
The doc wanted us to try another formula for 2 days.
She may be lactose intolerant, i suppose.
I wonder if she just finds the formula too rich and creamy compared to BM.
