Hi Narrawallee,
Thanks for including the photo link, I didn't know what a yo yo toy was! They are very cute. I teach at a preschool, in an infant class and I can tell you that EVERYTHING gets put in their mouths. It's how they play with toys, by mouthing them. So soft rubber would be a good idea. Just make sure anything you put in your toys is machine washable. Our toys get washed about weekly, sometimes more often.
Also, the antennae on the toy with the green face looks like they might be pipe cleaners, if so leave them off a baby toy. If the dog ears are felt, make sure you stitch around the outside edge, otherwise the babies will chew and shred it and get pieces of the felt in their mouth.
I hope this helps.
