Awake whole night. Make him sleep night?

My baby 2.5 months old is slowly increasing his night awake schedule. From 2days in daytime eats every two hour and sleep, play for 2 hours too.  But after 10 pm feed in night hes awake till 4 am. Doesn't sleep. Theres lot of things we do between this time lik feed enough swaddle him rock him after evey feed. Even if he sleeps only half an hour. He likes to talk and laugh seeing walls, hell keep staring at it. But cries after sometime. only  after 10 pm He keeps nippple only for 2 sec, pushes me, again suck 2 sec again pushes and stares at things. In this way he doesn't get feed properly. Its paimful for me because hv to latch him mamy times. As he removes mouth out of nipple many times. Why is he not feeding continuous lik daytime??? I tried using dim light still he lik to stare between feed. And cry if i stop giving him feed. I give 2 hour feed both breast. then formula as he bites hand or bedsheet. still hungry after 30 min. how to make him sleep night?? awake daytime
