That's 9... the 10th would be a universal remote control into which all 9 functions could be programmed and integrated. Motherhood would've been so much easier, don't you think?
P.S. I thought of an 11th - a teleporter. But teleporters require quantum physics and molecular biology on some level, which sound expensive. And expensive probably couldn't make it into a Maternity Ward Goodie Bag. Pity.
