Rated 5 out of 5 by from Love it My son was born at 34.1w - we use neosure & love it. He’s been growing like crazy & doesn’t seem to stain clothes!

Rated 5 out of 5 by from 36w Twins- Peditrician Recommended Our twins were born at exactly 36 weeks. This formula was given to one twin in the NICU and then recommended for both once they left the hospital. The babies have been gassy and spit up some of the formula occasionally, but overall it has been a great product. I am doing breastmilk and formula whenever my supply dips. So far, the twins are gaining weight as expected by the pediatrician.

Rated 4 out of 5 by from Works great! My daughter was born 34 weeks 4 days and needed to add this to her breast milk to gain weight and leave the nicu. Works great has been on it for 2 weeks only thing is I noticed is she has become very gassy and tries hard to push it out. Other then that its an amazing product!

Rated 4 out of 5 by from Great product My daughter was 5 lbs 6oz I breast feed and she’s on the Neosure since she was born. But since my breaks supply is low we have been giving her more formula and I notice now that it’s making her gassy. But other than that it’s been great for her weight gain because she’s almost 10lbs

Rated 5 out of 5 by from Preemie Twins My Twins were born at 30 weeks. Being premature this is the best formula for them. They are 4 months old today and they are growing so fast! NeoSure and Breastmilk are amazing for babies born early. !

Rated 4 out of 5 by from Gained weight! I had my baby at 36 weeks. She was born 5lbs 1oz. She’s been on break milk and formula since she was born... I just stopped breast milk because I thought it was making her gassy. she has gained 5 more oz but it does seem like she’s straining a lot to use the bathroom, she’s really gassy and constipated. She wakes up out her sleep whining because she’s trying to go.

Rated 4 out of 5 by from Needed for weight gain Twin preemie girls, at 3 lbs they will need this for awhile. Gas seems to be a problem,but they are gaining weight. Cost is an issue when you have twins. It’s sad when they don’t finish a bottle and you have to throw it out!

Rated 4 out of 5 by from Great formula It's a great formula for premature babies as my son was born at 35 weeks. And they gave this to him in the NICU to put on weight so I could bring him home. Hes 3 weeks now and the only thing I would say is that it does give him gas. But other tha. Thay hes growing great
