Every baby is different and some babies feed more then others. As long as they're not worried you're all good. I believe the general rule of thumb is that there fist is roughly the size of their stomach some babies will eat just that and others more.
My baby is 22lbs and 92nd centile, up from 71st😅🤣 once they start moving about a bit more they’ll drop a bit x
HV told me the only time they expect a baby to increase in centiles is whilst weaning so I definitely wouldn’t worry about it x
We've jumped a few percentiles since weaning too I think they are just foodies, he has 5 bottles and 3 meals don't worry at all it's great at this age
