So mopping can be a challenge when you have an 18 month old (he's actually 19 months, but I don't like to say that). He just gets in the way, and tries to take the mop from you.
So thankfully Daddy had a pile of old white t-shirts that I could tear into strips, then tie together with an elastic. I tied the bundle onto the stick with elastics too.
He stayed occupied until I was done mopping. Then his sister mopped after him. SO, my floors were the cleanest they've ever been!
