Do babies gain weight on Alimentum or Nutramigen?
Yes, generally. But breastfed babies and babies on hypoallergenic formulas (e.g. Alimentum and Nutramigen) may tend to gain a little less than babies fed on standard formulas. Note that, if your baby has digestive difficulties even on the hypoallergenic formulas, that alone may prevent your child from gaining as much as she might otherwise.
