Sleeping thru the night

Jacky

So my now 9 months old used to sleep thru the night even tho he was exclusively breastfed till 6 months and we are still breastfeeding. Since getting pregnant he's way too attached to me. So much that he'll cry every 1-2 hrs at night, and he doesn't even feed, it's more like comfort. I can't leave him there screaming bc he will not stop. Idk what to do, I want to have at least a night of sleep before the not sleeping stage of the pregnancy starts.
