Maddie is constantly moving and diaper changes are like herding cats.

I keep a small basket of toys nearby so I can occupy her with them while I change and dress her. It buys me a few minutes, otherwise she's practically rolling off the change table or rolling over.
She doesn't mind playing alone but when she's had enough, she's had enough right then and there. There's no waiting with her. She still loves to be entertained but she's getting better.
As for gas...my girls both stink so bad sometimes I don't know if it's them or DH!

It doesn't cause them discomfort but gosh, they can make a trucker blush somedays.
