I started out holding Sasha over toilets and sinks. Then I started holding her over a hospital basin on the kitchen counter (great height!). Then I finally ordered the BBLP. It was an easy transition from holding her up, supporting her thighs, to settling her onto the potty.
Sasha has really taken to the potty! I think it is a more clear signal to her that it is time to go. She pees almost every time I put her on it! And she loves to sit on it and kick her feet. I still sit her facing away from me so that it is most like when I held her for potty time. She can't quite sit up on her own, so I've found this to be a great way to support her.
The plastic can get a bit cold, so sometimes I fold a cloth diaper to tuck between her backside and the back rest. She mostly doesn't seem to mind the temperature of the potty, though.
I love our BBLP! I know there are other potties out there, but I can see why this one would be preferred.
