Re: Advice needed - 5 months old not gaining weight
with the PP. The AAP policy statement on breastfeeding says something like "the early (prior to 6 months) introduction of solids does not typically increase the rate of growth and only substitutes a food which lacks the protective qualities of human milk" (that's not quite the phrasing but it is the gist).
One thing you might want to do, in addition to nursing more, is to give a daily multivitamin. I think docs occasionally recommend cereal because it's fortified with iron, and if a baby is anemic a little cereal can help fix that. But far, far better to give a dropper full of baby vitamins than a bowl of cereal!
Is your baby highly active? Babies who are early achievers in the physical realm often drop percentiles as they start devoting more calories to motion and fewer to fat.
