Toddler bed

We have been trying to get ready for the new baby and we really wanted to get Hayden out of the crib. If he would allow us and do good with the crib front off, we decided we would buy him a bed. After weeks of trying with the crib turned into a toddler bed we went and bought him a new bed! He loves it and is doing really good! I made him a train (choo-choo) blanket and matching pillowcase. He woke up one day and looked at his blanket and bed and said WOW and laughed! He will also go and look into his old crib and say baby. Maybe he is starting to understand?
