@kaye87 I actually really like that book, and it's a great tool for kids at a more advanced level, but probably not for when I'm teaching my toddler the basics.
It only makes the J sound after special circumstances and J is just a few letters after further confusing things. It's like using centipede instead of cat. Anytime I see giraffe representing G I'm just thinking that they should have gone with goat. Sorry if this sounds incoherent, I haven't...
