So at just 22 months old, we're into a toddler bed.
Apologies for the terrible iPhone pics.
I was really nervous because there's only this short piece of rail to keep him in the bed, but he did perfect both nights this weekend! He got into bed and didn't get out, and slept all night. Both mornings he just lay there until one of us came in to give him his milk cup. He's climbing in and out without a problem. I did put some pillows along the floor where the open part is, and yesterday after nap he rolled off the bed but he was fine. Just got right back up and crawled right back into bed.
Phew! So glad the transition went well :) But where did my baby boy go? He's growing way too fast! Someone please slow down the clock!
