I also looked into the foremilk and hindmilk imbalance but it didn't seem right after I made sure she fully drained the one breast. The thing is, they are feeding more cos they are in pain and feeding is their only form of comfort. For us, the final straw was when I was sick with a virus and getting no relief from dd2 and told my husband to get a tin of formula to give me a break. As soon as she finished the bottle she had a rash all around her mouth. Being unwell myself, it didn't click. I thought she was suckling the bottle very hard. By the second formula feed she developed a rash all over her body within minutes. I then felt like the worst mummy ever and went straight onto a non-dairy diet.
