How to get my son to sleep in his crib the whole night?

Is that his own room? Id only suggest giving him a separate room as when he wakes up he will see nobody is there and it'll make him practice to lay back down and sleep. Could you offer him a teddy bear or a comforter he can cuddle?

Could he be ready to move out of a cot?

he doesn’t have his own room yet, we have only have 2 bedrooms and his uncle is living with us, but I am planning on turning the laundry room into his room for Christmas

he might be, he sleeps on a cot at daycare and they said that he’ll only sleep 20 minutes at a time and he wakes up panicking if he can’t see them

being on his own will allow him to learn, and you could maybe get a floor bed or even a normal adult single bed and put a side on it. My son sleeps the whole night in his bed he has his usual looking out the window and trying to open his bedroom door but he does climb back into bed eventually and sleeps. We have a child gate on the bedroom door also for safety. But in the meantime you could try a different size bed, try a comforter or teddy bear, is there anyway you can make the room darker as I can imagine the light nights are keeping him awake? Also would a white noise machine maybe help? Could you try maybe leaving him for a period of time to see if he will self settle back to sleep, because if he knows you will go back into the room he probably won't settle on his own. I know it's so hard to leave your little one to cry, scream etc but maybe give it a go one evening? Leave him for about 10 minutes and extend the time by 5 each time?

And maybe when you're in the room with him sleeping, try ignoring him he could lay back down to sleep. Or you could try getting into a routine where you tell him to lay back down it's still sleep time give him a cuddle and a kiss.

20 minutes is when they tick over into a deeper sleep so they look for the thing that helped them fall asleep in the first place.

My daughter has a floor bed (hers is a double mattress just on the floor, no sides)

Really common for them to experience separation anxiety at this age! It could be that he’s just wanting to check in! I’d also be looking at his daytime sleep as well and making sure he’s got enough sleep pressure to stay asleep once he’s gone down! X

Just based on what’s working for house guests right now - they have a 3 year old and a 14 month old . We started the little one in a pack and play in their room, and the bigger kid on a mattress outside of the room. They’ve swapped the little one and bigger kid due to the little one not staying in his crib. It’s been working quite well! Not an immediate change, but things have been getting better night by night.

the room is pitch black if I don’t have the green night light and he doesn’t like it because he can’t see what’s in the room, we have the ac running constantly and he does okay but idk if I should get an actual nose machine to see if it helps, I have been leaving him in the crib for 10 minutes before I go in and lay with him for about a month now but everytime I try to extend the time it takes him longer to go to sleep

he goes to daycare during the day and they told me he’s up every 20 minutes to see where they are at, but when he naps on the weekends he’ll sleep 2-3 hours maybe waking up 1-2 times

how long between naps? How long does it take him to fall asleep at night? If you were to lay with him does that help? Does he get a lot of one on one time with you during the day? X

it’s about 5-6 hours between naps, and normally he’ll go to sleep within 10-15 minutes, I lay with him now and he wakes up in the middle of night wanting me, he spends a lot of one on one time with me, every night after daycare he sits on my lap, and then on the weekends he eats and sleeps with me and sits on my lap
