Looking for anime for babies/kids.

I live in Japan, wife is Japanese, I'm American, and we want to make sure our infant son gets exposure to Japanese and English. When all the kids shows are on, he's at an American daycare, so he doesn't get to see any of the Japanese TV shows.

So I'm looking for some recommendations of shows similar to "Okaasan To Issho" and where I can actually download them. I'm looking for full episodes, not just clips that are on YouTube. I want to be able to download them so I can load them on our HTPC so my wife and son can watch them any time they want.

Seems like all of the anime sites I have found just have more adult oriented anime, every time I search for something related to kids anime or shows for Japanese babies, I get no results. But I get 6 million hits for High School of The Dead, haha.

So just looking for suggestions for places to download any anime for infants/kids.

Thanks!
