SLEEP TRAINING - 15 MONTH OLD

Does anyone have any tips on sleep training a 15 month old to sleep in his crib?

- Cry it Out method or better?

- I have tried setting him down in his crib after he falls in my arms, but he immediately wakes up, stands and grabs for me - no matter how many times I try to lay him down. 🥺

- About how many nights does it take? (I understand every baby is different)

- About how many hours each night?

- Should I do this for naps too?

- Will he eventually go to sleep without crying?

Thank you in advance!

* EDIT: currently co-sleeping

* EDIT 2: Thank you SO much to all of you kind and helpful ladies! I’m staying anonymous as I was bashed before for co-sleeping (sometimes some things don’t work for all babies as you know). I am screen saving all of these responses to see which works best!

And I’m assuming if I’m going to sleep train him for bedtime, I should do the same for naps? Or can I simply just let him nap anywhere?
