We've got the WW one too and a family circle one. They're both good but I prefer the WW one.
We also have the kid's party cakes book from WW and I love it. I start looking at it about 2 or 3 months before the boy's birthdays lol. I'm going to be shattered when they're old enough to choose their own and I just have to follow orders instead choosing myself and if they ever want a Lollipops party or similar where the cake is provided I think I'll cry....
