We also initially kept nawab in his crate. This way it was easier because he barked when he wanted to pee. But also be patient he might cry alone in the crate. They miss their moms and thus disturb at night
Puppies under 6 monthd of age should not stay in a cratvfor more than 3 hours at a time because they cant control their bladder or bowels for that long...
I also faced this issue , he sleeps with me since he is with me , After some training he doesn’t pee on my bed , he will get up from bed and do it on side , but sometimes if he can’t control he will do it there only once or twice
