I am considering these eco- friendly ones from Sevi, an Italian maker of wooden toys.
The colours are much easier on the eye and the designs very charming. I like this circus theme below.
His granny sent a Flensted mobile of elephants and it's floating above Z's changing mat now.
The other alternative is to ignore Z's needs and go with something larger than life. Something massive that will hang in the middle of his room. An art piece more than a playful mobile.
This is by artist Leah Pellegrini are made from hand blown glass. It is 2 feet by 2.5 feet and cost USD 145.
This is my absolute favourite. The red maple leaf branch at USD 595. How magical to have this just floating in your room don't you think?
You can buy them all and see more designs here.
