Any advice on how to make my toddler sleep a whole night on his bed?

No advice but here to offer solidarity! I'm in the exact same position, mine has slept through the night exactly 2 times his whole life 🫣

How long has he been in his own bed for? I had similar with my daughter where I slept in her bed with her x

Wishing you luck. We didn’t get full nights until my stepdaughter turned 5. (6months ago) Although adding a weighted blanket and weighted stuffed animal helped the process. Now she sleeps all night every night. But someone still has to lay with her until she falls asleep because She still won’t accept going to bed on her own. She also runs hot and has a hard time falling asleep if it’s too warm.
The fact that she still sleeps with mom (mom lives alone) made the transition take much longer than what I think it would have.

If he's under 3, he unfortunately may not have the impulse control yet to just stay in his own bed. He wakes up, he wants to be in your bed, and since nothing is stopping him, he goes there. I don't know if anything will help this except for repetition and consistently putting him back, but it may be outside of his developmental ability to stay put right now.

I have a boy the same age and had my daughter last spring, my husband sleeps in his bed with him and I sleep in my bed with little girl, it’s a sacrifice me and my man have had to make to ensure everyone gets a decent night sleep but we are starting to try days where my husband stays in with me and only goes to him if my son cries for him in the night (which obviously he does but it’s getting later)

I have a 2yrs old little one who does that too, but we keep taking her back to her bed, and we tell her how it’s more comfortable for her. She now spends more there and whenever she wakes she just wants us to tuck her in again and maybe lay with her for some minute.
It’s not nice having to get up multiple times.
He’ll probably adjust in time🤗🤗
