How hard is it, really? Start with nothing that requires a battery (people will thank you for it.) Next, eliminate plastic. Next, eliminate "modern" things - e.g. leave the wooden car at home, bring the wooden duck that Evil Auntie Sue gave her for Christmas.
So I rummaged around etsy, and found a couple of neat toys from Little Sapling Toys on Etsy.
I think she likes them.
Damn it hawkyns , this is entirely your fault.
