Any Japanese speakers on here?!

Allycia
Hey, so I'm wanting to do my (hopefully soon!) pregnancy announcement to my partner and need some help with Japanese. He's Japanese/Chinese, born in Canada but grew up speaking Japanese with his family. We have talked about him speaking to our future kids in Japanese so I thought a cute idea for an announcement would be giving him a book about dads (like a me and my dad book) in Japanese and surprising him that way! Any recommendations for a nice book would be amazing! Google translate isn't much help! Thank you
