My daughter had to be put on end amok reguline for constipation. It has helped some but it has gotten worse so now her doctor has her in miralax twice a day but I only give It to her if I noticed she hasn't pooped in more than two days.
majority of people I know that are on wic usually have similac advance. but if your baby has a different milk and isn't doing too well with it get a doctor's note stating your baby can't have that milk and take it to wic office.
