A week and a half ago my son had been having several nights of having a really hard time going to sleep. He would scream and cry and fight us at bedtime. Prior to all that, bedtime was no problem. Lay him in his bed at 8pm and he was out like a light on his own. I tried it all. After 5-7 nights of it I decided he would have to cry it out (he is really strong-willed) so I knew he must just be realizing if he screamed, cried, and fought us he would get what he wanted well that night he climbed out his crib....4 times. So, since then we have had to make a very quick transition to a toddler bed. We even lowered his crib down once more and he still climbed out. I was hoping to keep him in it much longer than 19 months but I am afraid at this point he will get hurt because he is so good at getting out. His crib transitioned to a toddler bed by taking the front off and putting a guard rail on but the problem now is getting him to go to bed in there alone! We were on vacation all last week and he had to sleep with us because there was no bed for him...I stayed in there until he fell asleep for the last 2 nights but he is waking up crying in the middle of the night. I am at a loss of how to train/teach him to stay in his bed. Being that he is only 19 months old it is hard knowing what he understands too. He also can climb the wooden gate in his doorway so I am not sure if I should shut the door and put a doorknob guard on the door but am afraid of what he may get into with the door shut :) Advice needed!!! TIA ladies!!
