N.D.
OMG 3 weeks really? Im mean seriously people will think that ludacris to put him on milk so soon but my daughters started at 10 months and preferred table food to formula. If they are getting adequate nutrition, frutis,veggies,grains,milk then i wouldnt worry. My pediatrician (who has children as well) said it was fine. Nutrition is nutrition , who cares whether its formula or milk!
