Quoting mommommommyma:" Ever since I made the complete switch to formula ( similac neosure ) baby has been so constipated. He's ... [snip!] ... when he does go he acts like it hurts a lot when he pushes it out. He is about 6 lbs, 5 oz now.... What could I do to help him?"
neosure is LIQUID GOLD
that said... question. are you using ready to feed, or powder?
if powder, are you mixing one bottle at a time, or a pitcher at a time?
neosure is VERY rich. it's VERY easy to screw up mixing by a TINY little bit, and it changes the product enough to cause constipation
i was using ready to feed, then switched to powder, and both girls isntantly became constipated.
my advice is 1) mix a pitcher at a time, not a bottle at a time. that way, small errors won't be as dramatic
2) get a scale. you can pick up an electronic scale for super precise measurements, and use that instead of the scoop.
