Are these safe for babies? I was thinking of getting these for my youngest for Christmas.
If your DS doesn't mouth objects, I'd say go for it. My DS (24mo) LOVES his kit. He has trouble with the single and double links, but he can use his palm to apply enough downward pressure to snap the longer links to the board. The integrated circuit pieces are bigger and easier for small hands. And, nothing stops him from giving me detailed instructions and outsourcing the fine motor work!
I don't know if all kits include the fan- that and the music IC are DS' favourite components.
