Lately Brock likes to sleep on his side. If I get him into a deep sleep in my arms, I can lay him down and steal an extra hour or two in the mornings to get things done around the house or with the girls. I confess he's a bit spoiled and mostly spends most nights sleeping on my chest or in my arms. Not because I'm prone to doing that -but because it's the only way he'll stay asleep at night! The co-sleeper? 5 minutes, sometimes 10 before he's awake and crying. I think it's because he doesn't like to sleep flat on his back. The last two nights I stuck a pillow under his mattress to elevate it a bit, and that did help, but he's also a roller!! and this morning he had rolled sideways on the incline (: O well... I don't mind sleeping with him in my arms, he's awfully sweet!! (:
