Is my daughter too big?

My daughter is 6.5months and she's a little chubber. I love it and I think she is perfect but people are always commenting on how chubby she is

... and I went to a parents group and there was a 8 month old and a 10 month old who weighed less than my daughter by a few oz. She is relatively short... around 26" but she is already 18lbs10oz. Is there a chance I am over feeding her??

I feed her usually 4 bottles (I mix 3 scoops of formula with 6oz of water which after mixed comes to about 7oz)

2tbs of fruit for breakfast

2tbs of cereal for lunch

2tbs of veggies for supper
