Is this too little

So LO is 14 weeks and eats 4-5 bottles 6 oz per bottle every 3-4,5 hours. And nights he would sleep thru the night,just sometimes waking up around 5 to eat and that’s it.But sometimes I will put pacifier to see if he is hungry it he falls asleep immediately so I just assuming he wanted something to comfort him(that can be around 3 am and he doesn’t show hungry cues).

So I’m wondering is this little of formula if he eats 4 times a day that is 24 oz and I’m worried he will lose weight.He is 17 lb
