If you are concerned, maybe book an appointment with a child health nurse and/or pediatrician. They will check your child to see if they are in the healthy weight range for their age, and also check your kids eating habits. Then they can determine if some modifications need to happen.
I know my kid has spent a lot of time indoors the last few months and had some winter chub, despite her very healthy eating choices. So any chub she has put on, is just winter chub. But in the last week, I have noticed her starting to slim back down again, and still not outside much, so must be a growth spurt.
Outside of that, I would look at yours and Dads body type. E.g. My eldest daughter is tall for her age, healthy weight, but it’s mostly torso length, as she has “stocky” legs/butt. But I have always had thick thighs and Dad has a thick butt, so while she can fit a size 4-5 in leg length, she needs size 6 to fit for her thighs and butt & size 6 tops.
