Cheyenne • Adalynn Layne Is My World😍💕

My baby eats about 3 ounces every 2-3 hours. In the morning I produce around 9-10 ounces but the rest of the day I get maybe 2-3 ounces every two hours.. should I be worried about supply? He hasn’t had to take much formula thankfully because it’s a hassle trying to get him to take it. Any tips?
