Well, honestly, I have been a little stressed about the sleeping situation with baby boy, but wasn't I pleasantly surprised when I woke up at a quarter after eight (!) this morning after having last fed him at 12:30. I don't know why I was stressing. He's always been a night owl.
I think where Theona would sleep her longer stretch first, then wake to eat every four hours, he settles in for his longer stretch later in the night. He did sleep in his crib last night, which I think helped him sleep really well. Yay.
So, problem solved. Why was I stressing?! I should know they're all different; I can't expect him to be just like Sis.
Thank you Lord for clearing things up for me.
