Like a PP said, we just put a laundry basket in the tub once the girls outgrow their baby tub. Works really well and is a lot cheaper. Once DD2 can sit up well on her own, she'll be in a basket while DD1 takes her bath.
Haven't gotten it yet but I want this one for LO from target. we have the angel care inclined seat and Hudson is trying to sit up in it so I also want something he can sit up in but is supported.
Re: Btdt bath seats
Samesies! She's in the "sitting" side now until I rinse her hair, then I put her on the reclining side.
