Hello girls, moms! I wanted to ask, we used Nutrisol Premium before and now switched to Nutrilite Comfort which eases colic and constipation from last night but he started crying really badly even though we give him every 4-5 hours and we have a GVB but he still wants to eat what should we do? Even don't know that he slept only 4 hours at night, we are 1 m 3 not days, what should we do? Please help us.
