Dosage and help with Prilosec

My DD was diagnosed with silent reflux at 5 weeks and put on zantac. It
worked for a while and then stopped so we did 2 dose increases for
weight. It still stopped working. My DD is now 17 weeks and weighs
almost 13 lbs and was put on Prilosec powder packets 15mg daily. She’s
been on it for almost 2 weeks and I am seeing some slight improvement in
her eating but she still has wet hiccups, congestion and will only eat 3
oz bottles with distraction. Is this a good dose of prilosec for her
age and weight? Should I be trying for a higher dose or something else.
I hate this silent reflux!

She’s not sleeping well either. Prilosec
isn’t known to affect their sleep or make them wired is it? I’ve heard moms say that prevacid affected their LO’s sleep but not prilosec. Anyone experience this with prilosec?

Also, she’s on the prilosec (omeprazole magnesium) delayed release
granules (powder packets) that we mix with water. Anyone use these with
success? We use 1 1/2 packets a day 10mg each for 15mg total daily.

Thanks for your help!!
