6 week plus and sleep more than 5 hours throughout the night without feeding is it normal?

6 week plus and sleep more than 5 hours throughout the night without feeding is it normal? Should I wake him up for feeding? I realise he was feeding 2-3 hrs in rhe day. 90-120 ml each time. He was 90ml since 3rd week but on the 5th we realise it has no longer satisfied him so after adding 30ml he stopped crying after feeding (90 + 30) and eventually we feed him 120.
