Just had our wic appointment they took my sons weight and height his weight is in the 98th percentile and height

is 83 percentile and they said he’s overweight and they want their babies lower then 80? He was born at 7.4 pounds and exclusively breastfed never given a bottle started solids once a day at 6 months and he barely eats now he only nurse 4-5 times a day and they kinda make me feel like I’m a horrible mother like my son is super fat i only fed him breastmilk so not sure why he’d be overweight I’m pretty healthy.
