6 weeks old baby girl

Hey everyone,

Just a few questions on here.

My baby has reflux and was on Zantac for about 2 weeks but that didn't work so the doctor prescribed Or fast tab and shes been on it for 3 days. 15 mg once a day.

But I don't think it's working as she wakes up every hour at night crying and during the days shell be awake but crying too. She also spits up a lot.

Also, how often should a 6 weeks old feed?

Or sleep? She has been awake more often now.

Please help. Thank you!
