Baby Slept in Crib

My son is 9 weeks old and he slept in his crib throughout the whole night for the 1st time.

I brought him a baby lounger nest a few weeks ago and it works great. 1st he slept on it on the couch (with me there supervising the ENTIRE time). Then hubby and I put the lounger in his bassinet. Took a few days for him (my son) to be okay with that. Then we brought the lounger over into his crib. That also took some time lol. We would bring the lounger from our bed to the crib for a few nights and vice versa until he would stay in his crib. Im so proud of my baby!

He woke up for feedings every two hours. Should I seek for ways to get him to sleep more over night or is that something that comes natural for babies?
