If you see your one year old and 3 year old sitting, playing with their tiny tea set, complete with water for tea you have two choices:
1) say “Oh, how cute”
And then go on with your day in blissful ignorance while they happily play and entertain themselves, or
2) say, “Where did you get that water?”
And then freak out when you realize they are drinking water from the toilet. Spoil the fun by taking away the entire tea set and sterilizing it in the sink in hot bleachy water. Strip their toilet watery clothing off. Consider washing out their mouths with soapy rags, but then decide against it and so vow not to kiss them on their mouths for the entire day. Wash the floor where they were sitting as well as the trail of water that leads right back to the bathroom where you spy the toilet brush in the toilet bowl like a huge stirrer, because the toilet did not have enough germs on it’s own. Dry heave a few times. All while the children cry and carry on because the water was “a-whish-ious”
If you are faced with this same scenario, chose option 1. That is my advice for today.
