We decided to take my son's paci away cold-turkey on his 2nd birthday. The first 2-3 nights were surprisingly great... it took a little more coaxing to get settled, but I considered it a win. Then all of a sudden he started FREAKING out when we'd put him down at night and would also wake up screaming even after being asleep for a while. Come to find out there's a 2 year sleep regression - fun. As part of his breakdowns he's started climbing out of the crib. My questions are 3-fold.
1) How long does this regression last?
2) We'd be stupid to give him back the paci for bedtime, right?
3) Do we have to move him to a toddler bed now?

p.s. he was previously sleep trained to perfection and with his paci was definitely a STAR sleeper.
