Sleep training

Words of encouragement please?. Secret you may have? Anything!!!

October (15mon) baby had surgery and I was so worried he was in pain I let him sleep with us. Then he got coxsackie in November’s and same thing.

Fast forward to now. My 20 month old sleeps in his crib for maybe 2-3 hours then wakes up and screams till he comes to our bed. And pretty much goes right back to sleep. He goes crazy until I take him out of his room and into mine.

Issue is that he doesn’t sleep in our bed either. He’s up all night kicking, turning, crying….

He has never been a good sleeper. Before all this I was up 5-10 times a night to put him back to sleep.

Want to start Friday. But like. HOW.
