Thanks Kim, for putting my mind at ease.

The only time that P-Pod cries is when Sweetpea goes in to see him. He has never cried after he feeds, just goes right to sleep.

I forgot to ask a few more things. Is it normal for the babies to jerk in their sleep and have what seems like the hiccups. There are also times that he seems to be panting and I feel it isn't too hot in my room, just comfortable.
Are these all normal also?
