Anyone transition their toddler from a crib to toddler bed before age 2? I wasn’t planning to but my son was climbing out. It’s been 5 nights so far and last night was by far the worst. He was up from 12:30-4:30 and wouldn’t go to sleep 😩 He has slept through the night his entire life so I just don’t know what to do.
