My Collin has been climbing out of his crib-or rather pack-&-play for weeks now. So we set up the brand new crib we just got this morning, and of course he climbed out of that as well.. So it is official.. At just 15 months old my itty bitty baby boy (he is still so small to me) is officially in a toddler bed, well at least for tonight.. We are trying it out. Fortunetly we have an extra crib mattress so I laid one on the floor next to the crib/toddler bed, just in case he falls out.. Man I am a nervous wreck. When did he become a toddler?
