Re: 4 Month Old Pulling Off, Arching Back, Straining/Gruntin
It sounds like one of those weird baby quirks that you just can't put a finger on. Maybe he's full and wants to let you know that he's done nursing. Maybe he's uncomfortable- needs to burp, needs to poop. Maybe he's tired.
I assume weight gain and diaper output are both normal?
Coolest thing my big girl said recently: "How can you tell the world is moving when you are standing on it?"
Coolest thing my little girl sang recently: "I love dat one-two pupples!"
