DS is almost 20 months and after sleep training has been a pretty good sleeper (put him in the crib at 7:30 and STTN until 6ish). This past week he caught the stomach flu with a fever and sleep went to crap. The second night we had issues getting an overtired toddler to bed after tylenol failed and he had become so overtired he was hysterical. After two hours (and giving motrin which brought his fever down) we put him in his crib in hopes that he would fall asleep after some whining. But he got really mad and climbed out of the crib. He wasn't wearing a sleep sack due to the fever so I put his sleep sack on and he climbed out again. After eventually falling asleep on me we had a rough remainder of the night.

Hoping that it was just a fluke due to the illness, we started the next night's routine and he was hysterical and afraid of going in the crib alone. We've been doing a sleep lady shuffle and I've gotten to the point where he will fall asleep in the crib with me out of the room. But then anytime in the middle of the night he wakes up and stands I get so scared he's going to climb again.

Anyone deal with something similar? Were you able to delay the crib to toddler bed transition? I want to at least get him healthy first before making the inevitable transition.
