Sleep related to med timing?

My son Gabe is 7 weeks today. Up until this past weekend he had been sleeping fairly well at night, sometimes only getting up twice.

I think we hit a growth spurt over the weekend, and he was sleeping almost around the clock and only waking to eat – although he seemed to eat twice as much as normal.

For the past 3 nights, he has been sleeping for about 4 hours after we put him down, then gets up every hour or two for the rest of the night…and most of the time he is grunting and groaning.

He gets the 15mg Prevacid solutab in the morning (usually around 6AM) and then gets .7 ml of Zantac in the afternoon and again before bed. He sleeps in a bouncy seat.

Has anyone found a good mix of how and when to give the meds to help with sleeping? I think we’re going to try moving the prevacid to mid-afternoon and doing zantac first thing in the morning and again before bed.
