8 month old not sleeping through the night

Michaela

I’m not sure where or what I’m doing wrong but my son is not sleeping through the night he will be 8 months in less than two weeks and he still wakes up every couple hours. I’ve been trying to get him to sleep in his crib he will for like 1-2 hours but then he wakes right up. also he is struggling with self soothing he will not calm down unless someone picks him up idk what to do ? Or if this is normal
