Can i cuddle baby to sleep the whole night, or is it dangerous. Baby is 3 months old.

I wouldn't advise you to cuddle as once we are sound asleep, we won't know if we are pressing too hard on the newborn. There is danger to even co-sleep with them. For my newborns, I let them get used to sleeping at their baby cot till they are older like 2 yrs old, then we co-sleep.
