A few things I've learned from living with 3 boys (husband is included here.)

They all snore. It just gets much MUCH louder and more annoying as they get older.

They are obsessed with their private parts - at all ages. (Even in the womb. I have the pictures to prove it.)

I have four toilets in my house. I can go to any one of them at any time of the day, and there will be something floating.

If I have to go to the bathroom in the middle of the night, I find the toilet paper in the dark and wipe the seat off first. Trust me on this one.

They fart more than is comprehensible.

Even when they beg, I will not let them show me what just came out of their nose. And, when I find foreign particles stuck to my walls, I pretend it is play dough.

Not even a padlock (or an armed guard) at the bathroom door will keep them out when I am in there.

They secretly love to put on makeup - and they all want their toenails painted.

There's something very disturbing about them running through the house playing "super heroes" while wearing my underwear on their heads, and fighting each other with my tampons.
