Is he having enough wet, diapers and enough dirty diapers every day? This is around the age were your babies gonna start helping your milk supply regulate so let him nurse as much as he wants to. It may look like he’s still hungry but it’s called cluster feeding and that’s a way that your body is gonna know how much milk to make for him. It also can’t hurt to give him the milk you’ve already pumped. Remember fed is best mamma 💜 goodluck!
