Struggling to find the right formula for my baby girl who is definitely constipated. She’s 1 week and 6 days old.

I started her on the Enfamil from the hospital then switched to Enfamil Gentlease to help with her gas.

It only seemed to make her constipated and irritable.

So I am now trying a sample of Similac Pro Sensitive. She’s adjusting. No poop diapers yet to see and I can’t really tell if it’s making a difference.

What formulas helped with a constipated / gassy / spit up baby ? Any help would be great right now !
