He pooped, I changed his diaper, then projectile poop everywhere

He pooped, so I started to change his diaper.. he starts pooping again so I put the dirty diaper back under his butt. Get him all cleaned off and put the new diaper under his butt.. projectile poop everywhere.. this lasted for a good 2 mins.. got him cleaned up and put another new diaper on lol I've never seen so much poop.. hopefully he sleeps for 3 hours straight tonight lol
