Quoting Brittany♥Gracelyn:" At what age did you switch your LO's into a toddler bed?"
18 months... when I was about 3 months pregnant. We wanted to make the switch before the 2nd baby arrived so he didn't associate the change with a new sibling. It worked out super easy and we've never had a problem. Now the youngest is 18 months old and still in the crib... I have a feeling he'll be harder whenever we get around to switching him.
