My sample size is low, but I did cry it out with my son at 4 months old and he has slept amazing ever since. He is 16 months old now and he gets excited when I put him in his crib to sleep. He will often go to the crib unprompted around 7:30pm (his normal bedtime), as he is ready to sleep. I've had sleeping problems my whole life, so seeing him sleep so well is very satisfying to me. I will be doing the same with my second child.

We did sleep training with ours, it took two days and a solid sleeper ever since. I don’t think cry it out always works. But the side hustle is that you have a schedule and stick to it.
