My 11 month old son has recently been drinking a lot of water from his sippy cup. Maybe about 7-10oz/day (maybe more??). He is VERY active, and 80th percentile in height and weight. He also nurses every 2 hours and probably gets around 24 oz a day from me (just a guess here). He loves solids as well and eats heartily. His poops and wet diapers seem totally normal. My question is, should I continue to let him drink water as he wishes, or should I possibly consider introducing cows (or goats) milk a bit early so he has something a bit more nutritious? I don't feel like he really needs more calories, but maybe I am wrong. I really do not want to start giving him formula at this age.... Thanks for the assist!
