DS is 6 weeks Monday. We've been prescribed infant Gaviscon for his reflux. I'm worried because all I've read on here is that it's makes babies more unhappy becuase it causes constipation. Anyone have any positive stories about IG? Also I'm sure Dr said we could give our baby more than 2 sachets in 24 hours because he's over 4.5kg, but instructions on the sticker from chemist says 2/day. Instructions in the packet don't give dosages for babies under 1 yr!
