My daughter is 2.5 months old and on 7.5mg solutab of prevacid three times per day. She is still having some very upset times where she appears to me in pain. I have read on here about giving them the cherry supreme mylanta. We bought some tonight. Can I get clarification on administering it? I have read in other threads that it must be spaced 4 hours from a PPI. Does this mean 4 hours after and 4 hours before a dose? So if I am giving a prevacid dose at 8:30am, 3:30pm, and 10:30pm the only time I could use the mylanta would be during the night?
