What do your children play with in the bathtub?
Plastic toys that were given to my daughter over time...the "unwanted" type stuff that we try top get away with not having around the house(my little pony, etc), but stuff my daughter had a hard time parting with! We compromised and made them tub toys! We also use shells and some polished gem stones. I like the glow tick idea!
Cups and bowls, bath books and rubber squish animals which I need to throw out because they'r all mouldy inside. Won't be getting them again! A wooden boat (rubberband powered) and a wooden bird whistle. Plastic nesting cups.
I'm thinking of getting rings and a rubber duck that doesn't take in water.
I keep meaning to get sea shells for them for the bath.
I love the idea of driftwood, will look for some.
if you search the archives I'm pretty sure you'll come across another thread on this topic, I think I found one way back.
