Formula switch Enfamil A R..question!?

Kristin

Question!? My LO has acid reflux and the last week shes been in the most pain. Long story short..doctor wanted to switch her formula to Enfamil A R which so far has been great and I have my happy baby back aND has been sleeping through the night again. However, because the formula is thicker I am afraid she will get constipated. Anyone use this formula for their LO and put something in it to keep them regular? Or what do you suggest to do to help constipation? I have done gripe water in day and night but is that a safe alternative VS a juice? I also am trying to avoid apple juice to help her bc of the sugar but that is something my doctor recommended...what do u think ladies !?
