is this normal?

This might sound really silly, but i have never seen it before and i'm not sure if it's just another development he's trying to go through. My son is 7 months old, he isn't crawling yet but he can sit up on his own and rolls all over the floor. However, when he's laying down, for the last 2-3 weeks (maybe a little longer) he reaches his arms up to the sky and puts his legs up in the air bent, sticks out his tongue and kind of blows bubbles. i'm not sure if he's doing this because he's trying to learn how to sit up on his own or what? Has anyone else ever seen this? Do you think i should be concerned?

DD used to do that and she still does sometimes and she's 2.

i'm glad i'm not the only one who has a LO that does it ! i mean, i honestly think it's hilarious when he does it but i have never seen another baby do it before.

I wish my lo would roll over hes 6 months but was 2.5 monghs early he hates his tummy

My son hates being on his tummy too. He just rolls and keeps rolling but will only stop and stay on his back.
