Night feeding

Megan • Trying for our third! First baby a miscarriage, chemical then rainbow. Second baby 9 months of trying 4 with clomid. Hoping for a quick easy pregnancy for #3
My little one is just over 3 weeks old and went 4.5 hours without eating then only ate about 10 minutes on one side before falling asleep. I tried burping changing and everything nothing worked. Do you think this is ok? He ate about every 1.45 mins during the day.
