Baby drinking less ???


Anyone else’s LO drinking less formula/breastmilk??? My son used to drink 6oz every 3 hours. I give him a bottle first thing in the morning, 6oz but he doesn’t finish it, probably eats about 5oz. Then he has breakfast. After he wakes from his first nap around 10-1030 I give him another bottle and he only drinks about 2 Oz. Does he not need that bottle anymore? Since he’s eating 3 meals a day? I give him another one after his afternoon nap.. and he’ll drink that. And I give 7oz at bed time.
