A garbage truck cake?!
My internal critique started immediately after my husband cast his vision for our son's birthday cake.
    "There are entire books written about designing birthday cakes in shapes which I'm sure you're not planning to consult."
    "You're biting off more than you can chew."
    "I can see it now - I'll do everything to pull off the party and you'll be spending at least an hour just doing the cake."
    "How about just ice cream?"
But, this time I decided to just keep quiet. A garbage truck cake would be fantastic. And the less angelic side of me thought if it didn't work, I would come out looking pretty smart. (Isn't that mean!?)

Well, allowing him to make the cake paid off in many ways. In the most tangible way, it paid off because it was a tremendous cake which my son loved. All the other garbage-truck-loving kids at the party were wowed too. The other adults were very impressed. But, more importantly the experience allowed us to share more fully in the celebration of our son's birthday, my husband was able to use his creative & artistic talents, and we split up the work of the party. So often moms face the temptation of trying to control things. Regardless of which partner it is, often there's one parent who tends to have more responsibility for day-to-day caretaking, things like making lunches, getting the kids dressed, teeth brushed, etc. At special events, it can be easy for this parent to assume all responsibility for the arrangements of the event. But just like the day-to-day tasks, there are ways to share the responsibilities that lead to a richer experience for the whole family.

Good communication always seems to be at the root of success in some form or another. Patience also comes to mind.

With this advice to share each other's talents and abilities comes my blessing on your communication and patience! Good luck!
