Rated 5 out of 5 by from Both my babies have used/ currently using this formula Both my children have needed this formula. I love it. It has helped my son put back his birth weight and then some already. He was born 35 weeks 4 days. And my daughter has exceeded expectations and is currently a healthy and brilliant 4 year old.

Rated 2 out of 5 by from Good for weight , poor for bowls Had my baby at 37/38 weeks and even tho that is considered full term my baby was tiny for his game age weighting 5 pounds and 1 oz. So they put him on Neosure to make sure he gains weight which he is. But the thing is he is fussy and has had problems with constipation and he has just turned 2 months and that's bout how long he's had the issue. Plus with the gas as well.Not really sure what to do they want him to stay on it but my baby is miserable trying to pass stool and almost nothing is helping at this point.

Rated 4 out of 5 by from Great "Stuff" My baby boy was born at 27 weeks. He weighed 1lb, 14ozs at birth. He spent 2 months in the NICU. He was 4lbs when he came home. When he was discharged, they told me to give him Neosure twice a day and breastmilk. He wouldnt tolerate the breastmilk. (I know, weird) He is now on Neosure exclusively. He gained 2-3lbs in less than a month. The only thing that I had a minor concern about is, he is gassy and has trouble moving his bowels. It takes a few days for him to go. If you can figure out a way to control the gas and constipation Neosure causes, this would be the PERFECT formula.

Rated 5 out of 5 by from Awesome sauce My twins were born at 36 weeks , no NICU time . . this has been the one and only formula that they have been on . . they are now 6 months weighing 20lbs a piece ! I didn’t have to switch formula or go through the motions of trying and testing what worked for Them ! This was the first and only formula my boys have had to try out

Rated 1 out of 5 by from 36 weeks My daughter was born at 36 weeks and a blessing. We are now week 2 of her life and she has been constipated, fussy and extremely gassy on the neosure ilk We have four other children who were all pre mature due to my health condition but they never had any of these issues and was never on neosure. Gas drops help for a short period of tie but I should not have to give her gas drops after every feeding. I have made a doctors appointment for tomorrow to get her off this milk and so she can have a peaceful sleep.
