Should i wake up my lo who is 2 months plus to feed? Coz sometimes he will sleep thru out the night which like 7 to 8 hours.

Please don't wake your bub up, i know you maybe worried that he is hungry. But i always say babies are too smart. They will definitely make it known to us if something is needed. And in this case, if he is hungry. Chill out while he sleeps. Better option. :)
