So my 12 week old little fella went weeks where he would suck on his hand when he had a burp still roaming around in his little body. As of the last few days he's been chewing his hand more and I've come to learn, after many false burping sessions, that he was still hungry. I keep forgetting that they're supposed to be feeding on demand although sometimes he'll get 4 ounces out of his bottle and still be hungry like 2 hours later, whereas he was drinking his milk every 3-4 hours previously. I'm scared to over feed him because Lord knows I've been there, done that. Any who, just wanted to share with everyone just in case you're experiencing the same thing.
