My daughter did the same thing. It used to keep me up at night. I was breastfeeding but giving her a bottle of Enfamil LIPIL with Iron at night before bed. Then I switched over to just Enfamil LIPIL with Iron. It just seemed to get worse. Mylican didn't seem to work for her either. So we decided to try Enfamil LIPIL Gentle ease. It took a few days for her to get used to the new formula, but it really helped her with her gas and now she sleeps better at night, which helps me to sleep better.
