11 Weeks Baby Weight

Hi! My baby is 10 weeks 6 days, and around 5.35kg. Seems like he is in the lower percentile... He feeds between 750-800ml each day but closer to 750ml, diaper change between 5-9 times. Based on body weight he should be drinking 150ml x 5.35 = 802.5ml every day. I tried to offer more milk at each feeding but he cannot finish. Is there anything I need to do differently? 😮‍💨
