My Kid Does This....WEIRD?! Or??

Ni

So my little boy does some weird things sometimes lol! I was pregnant in November/December of 2016 and it ended in a MC December. He used to blow on my belly and laugh because of course he found the fart noises hilarious! Then after I had my MC he stopped. I fell pregnant again April 2017 which ended in a MC. I had a D&C; June 2. Also during that pregnancy he too blew on my belly and laughed at the noises. After the MC he stopped...he just walked up to me, lifted my shirt up and blew on my belly and laughed. I said Kaiden why do you do that? He said because I like it and ran away lol! Coincidence? Or is my kid just weird like me LOL! (Currently waiting for my blood work results)
