Some of these movements every baby makes within their first week, some are just reactions and not real smiles or meaningful movements, but I'm going to list them all here so that you can get a feel for how our little guy acts around the house.
Crying - duh. Poopy diaper, feeding time, burps, and bowel movements
Smiles - not real, but they look like smiles. They are accompanied by grunts and squinting of eyes. However, he does smile when feeding, and I noticed a smile not accompanied by grunts or squinting last night (really this morning) when I was rocking him. Those smiles do look like content but we won't mark them down as a real smile just yet.
Feeder finder - when hungry, sometimes he will turn towards your chest and start bobbing for a "feeding mechanism"
Arm movement - he has perfected some karate moves, boxing, the windmill, Mr. Roboto, and many other arm movements. He sometimes sleeps with his arms by his ears, up in the air, or as if he is announcing a field goal. Watch out for the arms as they swing violently when he is crying. He does hold his pacifier in and will pop it out on his own. He also blocks attempts to put the pacifier in. He does often cover his mouth and nose when he sneezes.
Leg movement - he needs leg room. He kicks during diaper changes making them difficult for daddy.
Rolling over - he has strong arms and can push himself off of his stomach and even roll over to his back. He can only roll from his back to his side at this time.
