Cain sleeps in a toddler bed at my Mom's when he spends the night there and does really well. Over the last weekend we went to stay with family and Cain slept in his own "bed" and did so good. So when we got home we decided to turn his crib into a big boy bed. We just took the side off and switched it to the day bed option. He was so excited! When it was time for bed he climbed right in and went to sleep. He did not get up once during the night. This morning when he was awake and talking he stayed in bed until I came in and got him up (which I am sure is short lived when he really realizes he can get up at his own free will). We are proud of him for being such a big boy!
