thank you

They recommend 2 to 3 oz . So maybe just giving him an extra one & he'll be fine. Well thats what my babies doctor told me. To wake him up every 3 hours and feed him 2 or 3 oz

You can go up half oz each time until you see he is satisfied that's what my doc said

Yes. They grow a lot that first month. Listen to him , but make sure he doesn't just need to burp, be changed etc too.. U never know. He may also want to suckle on something too??
