Sam has been upgraded to a twin bed. After finding him sleeping on the floor the last few weeks, we realized he had outgrown the toddler mattress. So we took apart the crib/daybed and moved things around in his room to fit his "big boy bed."
He's pretty excited about it.
This morning I went in to check on him and he was just laying in bed, awake, with a big grin.
Wish I could say I was as happy about his rapid rate of growth.
