My girl has been on Nutrumigen since she was about a month old. We believe she has or had a lactose intolerance but you know that's just what everyone's guess was. She had colic so who knows what it was. She's never been able to drink it alone without some form of help to get her to poo. I mixed with babies magic tea for awhile which helped plus chiropractic adjustments but the husband stopped all that🙄 Prunes on the daily help sometimes but she hasn't pood in 3 days & is constipated cause she keeps straining. I want to switch to a different formula & give it a try like the gentlease & see how she does on it. He agreed to try a different formula. I'm seeing the regular and the neuro pro & am wondering which one might be best for her constipation problem? We can only do Enfamil too because of WIC so not sure if it covers the neuro pro anyway.
