POD Children

I am pretty sure that aliens have come and replaced my three younger children with POD look alikes.  Either that or they have contracted some weird "I am doing my chores without being asked" virus.  For the past few days, Jessica, Josh and Daniel have been getting up, fixing me breakfast in bed and then doing all of their chores first thing in the morning.  Anybody who has teens, knows this is so not normal behavior.  Even though my teens are pretty much more helpful than most teens, this is not normal behavior even for them.  Now the conundrum--wish for my teens back, or keep the POD children?  I must think this through carefully!
