That is why I lock the bathroom door.
When I don't lock the bathroom door, either T or B are in with me immediately. When I say "really, dear, mommy needs some privacy", they pull the door closed, look up and say "privacy, that better?". (um, not really).
With the door locked, suddenly a house full of boys that were busy
Truly, can't this wait for a moment?
On the flip side, some day, I'll be up wandering the house at night (as I often do) and they won't be all cuddled in their bed to kiss in their sleep. I won't always have a two-year-old to snuggle from about 2 am until we get up.
Life is all about trade-offs, isn't it?
