BathTime Troubles

My son loves bathtime until one day I gave him a bath over at my moms house. I was letting the water out and that little slurping sound the water makes as the last bit drains out......terrified him. So after that it was only sink baths. But as he got bigger I missed the way he loved to be in the tub with his toys so with a lot of effort we eventually got him back in. Now I'm wishing we could just hose him down in the back yard.(no, really). Today I was giving him a bath and I usually put him on the potty first to see if he got to poop. After about 5 minutes and just a little tinkle I figured it was safe. WRONG. As soon as I put him in the tub I knew something was wrong because he wouldn't sit down. As I was going for the towel there was two quick kurrpluunk's...NOOOOOOO!!!!! But it was too late. So I didn't really know what to do. It was my first poop in tub experience. So I grap a plastic baggie and waited for the tub to drain. The scoop them up as I would a dog's. I cleaned the tub and tried again. If at first you don't succeed, try try again.
