My son had outgrown his infant bathtub at 9 months and needed something bigger (he's a 90+ percentile kid), but I wasn't quite ready to just sit him in the big bathtub yet. He was still a sometimes unstable sitter and I wanted us both to be able to enjoy his bathtime without worrying about him slipping or falling over. This froggie tub fits perfectly in the big bathtub, takes up about half the length of the tub, and leaves very little room on the sides of the tub - so the froggie tub itself sits snugly and doesn't move around in the big tub. I like the saddle horn and that it's not quite in the middle, it's slightly offset. It was too tight of a fit to sit him on the smaller side of the horn, but it works perfectly to sit him on the larger side of the tub, and the horn keeps him from sliding forward if he leans back, so the saddle horn is positioned so you can use it for a long time, first on the smaller side with a smaller baby, then put them on the other side of the saddle horn as they get bigger. The tub has a release plug on the bottom but I never use it - the tub is small enough that I can just lift it up and dump the water out by turning it upside down in the tub when we're done with bathtime. The only slight negative is that it was a little tedious getting the thing aired up the first time, but it's stayed inflated for 3+ months and I've never had to add air since it was first inflated. Plus, the froggie print is cute! :)
