We have been battleing gas and constipation for about 2 weeks. We wound up giving her a little Karo in her bottle and it got the constipation cleared up a few days ago, but she is SO gassy and uncomfortable. We have tried gripe water and gas drops on different days. She has been on Enfamil Enfacare since she was a bit premature, and in the last week (per doctors order) alternating bottle between that and Gentlease with no change. Anyone else experience this, and have any advise?
