Growing up

My kids are happily playing in the tub this morning.  They used to do that all the time, and now it's been months since they've been in there together. Sarah is a scientist who concocts various medications for a sick seal.  Noah is the veterinarian who administers it.  I'm savoring this sweet, innocent moment, because I know this may be one of the last times they play together in the tub.  They'll soon be too big.
