Nutramagien to gentle ease

Hey ladies

My sons on nutramagien.

He went to dr today hes been on it for ab 4 months now a little longer i believe (hes 6 months) well he was super super constipated only going balls pebble size etc so he got put on the nutramagien which worked wonders well today his dr said we should try normal formula agian to see how he is being now hes older. So she gave me samples. She put him back on gentle ease Enfamil which is what made him like this in the beginning (backed up , balls , crying etc) so i have super had anexity over it !

Any ladies lo have this problem and end up ok?
