6 weeks old baby drinking every 1.5hrs

Is it true that they say baby boy drinks more milk more often ? My 6 weeks old baby boy born @ 3kg and now is 4.9kg, fully formula fed and drinking 80ml/feed. First few weeks he used to drink every 3hr then it changed to mostly every 2hrs and recently past few days its only 1.5hr bt he’s already crying for milk and nothing can console him. I try to drag time by consoling him or taling to him, rock him, walk walk but nothing works, he keep crying and showing hungry cue. Like searching for nipple etc. Should i still give him if he demand even if its only 1.5hr? Mostly during daytime. Nightime after 11/12pm he would usually cry 3-4hrs. Im scared im overfeeding him and itll lead to health issue. But if according to calculation weight x150ml, he’s still within the range. Just that im scared of keep feeding him less than 2hrs. Since they say babies always feed 2-3hrs. Anyone facing same thing too?
