I love these guys: https://www.amazon.com/Boon-Scrubble-Interchangeable-Squirt-Multicolor/dp/B001Q3L8RY
They are squirters, but they have twist off interchangeable tops. Also a red plastic spoon from getting frozen yoghurt a few weeks ago. lol. And bubbles. Not the bath bubbles kind, but just regular blowing bubbles. Fun and pretty mess-free.
ETA: And just some plastic cups for pouring.
We have these...
They are foam too so it works great for teething!! lol.... They are small for their tiny hands and now that DD1 is learning to read, she spells out words on the bathtub wall. (they stick to the wall and tub)
We also found a little butterfly toy that has a net and 3 butterflies that swim around and they catch them. DD1 uses the net and DD2 just tries to catch them with her hands.
PS.... the butterfly toy was most definitely NOT that much when I got it! I think at walmart.....
R loves the Sassy Catch and Release fishing net and the Pull and Go boats. He also really likes bath books and bubbles.
We do have some squirty toys and always had other ones for SD when she was small and we never had mold problems because we made sure that the water was all squeezed out after use and I rinsed them (inside and out) in a bleach solution a couple of times a month. But it is a PITA...
