I have 2 dd's dd1 is 3.2, dd2 is 8 months.
Their collection of bath toys is pitiful - stacking cups & a tomy singing dolphin thing (singing dolphins don't work but dd1 has named all 8 so they stay anyway!)
So I thought I'd look for some for their christmas presents but I can't find any good recommendations , so please tell me yours!!
This thread is old now, so some of the suggestions may be outdated. Our best bath toys page has loads of great options for all ages, as rated by parents and their little ones. We hope you find it useful.
