Baby bath time suggestions?

Hello mamas? What are y’all using to help your 7-12 month-olds sit up safely in the bathtub? My son looooves playing in the bath, but he’s outgrown his reclining seat. I need something that’s easy to take in and out of the tub. I’m remembering those plastic rings that suction to the bottom of the tub from my childhood, but I can’t find them anywhere!!
