I have a daughter who is just over 6 weeks old.. and she's well what we believe suffers from colic.. it happens every night between 7 and 10, she'll cry no stop and wine as if she's in pain. Iv tried the doctor Browns bottles but not having any joy. I've tried infacol but that i found made her sick. I got told to try bigger teats on the bottles. Please I need some advice on what else I can try ... thanks #worriedmum
