Four months old and Rowan is almost the full length of the co-sleeper that his Daddy made for him. He's growing fast. Having a co-sleeper has worked really well, and is convenient if he wakes up in the middle of the night and needs to be fed. We have a crib/cot, but haven't needed to use it. So, in a few months when Rowan's feet are hanging over the edge, we'll need to see where he gets to sleep. Jen wants a bigger co-sleeper. Maybe I need to make an adjustable one that will last him until he's 18.
