This little boy often joins us in bed at some point in the night.
I think all of our kids went through this stage, but David is by far the least disruptive when he snuggles with us. Half the time, I don't know he's there until I wake up in the morning.
If I wake up, which is rare, I snuggle him for a little bit, then send him back to bed. But he's still and quiet, and he's a great snuggler, so we don't mind. :-) Sometimes, the rest of us get up and ready, and he just snoozes on. Such an easy-going little guy!
