Still hungry?

Jessica

So we went to my nephews birthday party today I brought two 3oz bottles of breast milk because I didn’t want to have to breastfeed. He started to get fussy and I tried to give him a bottle but he wouldn’t take it so I gave in and gave him the boob. He feel asleep for about an hour then woke up hungry. I gave him the boob again. He ate for about 1 hour I could hear him gulping and I could see he was getting milk . Then he fell asleep again for about 10 minutes and woke up and acted like he was hungry again so I tried to give him the bottle and to my surprise he drank all 3oz .. is he not getting enough from my boobs? Or is he just a hungry growing boy. He’s 3weeks old.
