bragging rights!

So I'm friends with two ladies and they both have boys. they are both older than my boy. today I was speaking with one about our boys weight (her baby 13months 18lbs mine 8 months 19.6lbs) and out of no where other friend comes over to brag that her son at each of our sons ages was x amount bigger and he's so big and chunky and that she could carry our babies in one arm all day because her boy is just such a "biggie boy" **she says this at least once a week while at church or while hanging out were all sahm) I don't even know what to think right now... what would you say to this? I'm honestly kind of peeved because I'm thinking wow can't we just be happy our boys are growing?!?!
