Worth mentioning the Tin Can phone: https://tincan.kids/

All their batches are sold out, I guess it’s pretty popular. Interesting tidbit, it needs to be plugged in at all times, not meant to be mobile.

Inspired by this I hooked up an old rotary phone to an ATA and got a number from a low cost SIP provider. Now my 5 year old can call his friends and family on his own. He loves when it rings and when he can call his pals to make his own plans.

It lacks the features and network effects of the tin can system but is still pretty fun.
