I feel like we've had to repeat sleep training a million times! My 26m old goes through weeks, even months of going to bed easily and staying asleep through the night. He's had good stretches since the first time we sleep trained around 6 months. But it feels like it never ends. Just when I feel like we've seen the last of it, he struggles to go down again. I'm trying to stay super consistent and do what we've decided we're comfortable with and what's "worked" in the past, but it's so frustrating!

Have you had to sleep train multiple times? If so, how old was your child when he/she finally stopped having regressions?
