Most three-year-olds are not still in cribs, having transitioned to toddler beds long ago. But in this case, Sprout is not “most kids.” He’s never tried to climb out of his crib, uneasy with scrambling down where there isn’t obvious hand and foot-holds. Because there was no great need, we put off the transition as long as possible. But with his third birthday passed, a potty-training blitz coming up, and preschool approaching, we figured it was time. It was only slightly more chaotic than we expected.
