What You See Here...

 ... is not a baby taking a bath in the kitchen sink.

No, what you are seeing is a diversionary tactic.  The water is diverting the baby's attention away from Momma, who he decided needed to hold him All. Day. Long.

The baby in the water diverted a certain three year old away from torturing his older brother All. Afternoon. Long.  Of course, it also made him extremely jealous of the baby, but listening to his demands of getting the baby out of the sink so he could get in was much better than listening to the battle cries between him and his older brother.

And the splashing from the baby diverted the six year old away from his video games, which he would happily play All. Day. Long.  If Momma let him.  Which she doesn't.

And what did momma do during this time?  Cleaned up the kitchen, emptied and loaded the dishwasher, started on dinner, worked on her calling, and anything else she could accomplish while not having to hold the aforementioned baby.
