I'm obviously taking my little girl to the doctors tomorrow but I just can't think of anything else or what I can do or what it is!!

She burps and farts fine and will settle after her bottle but 30 mins into being asleep she will scream and scream for hours..

at first I thought it was wind/colic but she burps and farts quite a lot but still screaming with belly ache? I've fed her at 7 and she's only just stopped screaming at 9:45 do you think she could be lactose intolerant?

I can tell it's definitely belly ache but I've just run out of ideas she's only 3 weeks old..

Any suggestions?
