Crib Transition

A

Where does everyone’s baby sleep? For the most part our little one sleeps in his crib, but on the nights he doesn’t sleep well I bring him into bed with us. I feel like he’s out growing his crib. If his arms are both stretched out to the sides, they are outside the crib. He’s constantly moving so he’s bumping his head, arms, legs all on the sides and it wakes him up. Is it too early to move to a bigger bed and add rails?
