We gave Kapri her first bath in the kitchen sink the other day. The sling I have for her to use in the bathtub is too small.. she's so stinkin' tall. Her poor bum rests on the metal bar at the bottom. Anyhoo.. she sits up really well, but I still don't trust her to sit up in on her own in the bathtub. I tried it once, and she's so dang slippery I can't keep hold of her. So.. we moved her to the sink. Its so easy.. and she loves it. She splashes like crazy.. which leaves me soaking wet by the end!!
