Is anyone’s little one on Nexium? My son was diagnosed with reflux at around 2-3 months and was on Zantac for awhile but it seemed to stop working so he was switched to 5mg or Nexium 11 days ago. I was told it could take up to two weeks to make a difference (he had a lot of screaming in pain, back arching and spitting up). Literally on day 7 he was like a new baby and so happy and comfortable. Today day 11 and his morning was okay and then his afternoon fell apart and he was screaming/ wouldn’t nap and seemed uncomfortable and spit up A LOT all day. Anyone else experience anything like this? We do have his 6 month check up tomorrow.
