With baby on the way in just 3 short months, we decided to go ahead and get Fischer used to his new toddler bed (which he thinks is a very big boy bed!). We were prepared for a few days of a struggle sleeping, but instead, when he saw us putting it together in the living room, he ran and got his puppy, blanket, and pillow to lay on it (even before the matress was there!). He took his nap in it a few minutes later, and hasn't had any trouble adjusting!
He made daddy try it out with him :)
I'm a big boy now!
