We've been doing formula for about 6 weeks now and have had issues for 5 of those. We started on Enfamil Neuropro and everything was fine for a week. Then my son started pooping 4-7 times a day, diaper rash from all the pooping and runny/stuffy nose.

Switched to Enfamil Nutramigen and the nose problem resolved. Still pooping 4-6 times a day with diaper rash doing better. Switched to Similac Alimentum. 5 days in and still pooping 3-5 times a day, but almost no diaper rash.

Any suggestions before I call my son's doctor for the hundredth time🤷
