RE: Finally discovered Gertie balls. Where to buy them?
We have several Gertie balls. Noah loved them when he was a baby and now the knobby Gertie ball is DD's favorite toy. I will say that Noah and my nephew now have little to no interest in the Gertie. They prefer 'real' balls like red rubber balls (like the kind at school), soccer balls, volleyballs etc. I think the red, rubber bouncy ball is the favorite because it kicks so well. It was a staple for kick ball and dodgeball when I was growing up. Just my .02 so feel free to ignore me ;) .
Anyway, to answer your original question, we always just buy them at local toy stores. If you google it there are a ton of websites that pop up.
