How does a "new parent" know more than me?

P.S.

I went in after an hour to lay "baby" to nap - she co-room-sleeps with 3yr old. dcg opens her eyes and I ask her (after an 1hr nap) do you want to wake up or sleep more....and she says "sleep more" and is still out!!

Both of my nieces and a dcg went through this too. All of them were 1 to 4 weeks premature and immdiately stopped this horrific puking/spitting up when they could sit up on their own. The doctors said that something in the digestive track did not develop before birth and this is the bodies' reaction.
