Is that normal? I am a breastfeeding mama and I noticed he will be in there for an hour sometimes but I started pumping for him and I am getting 4 oz to 5oz every time from both boobs together .. and he drinks every ounce 😩😩 he just looks like he’s gonna pop 😂 .. and then early morning 12am to about 5 am he will wake every hour to eat but I limit it to 2 to 3 oz I can’t keep up with him !! Any advice on getting a really big supply ?
