Mom and Dad

I had so many tantrum when my parents first moved in.  I was constantly worried that they will change our little love nest with their habits or clumsiness.

Now, I don't know what I would've done without them.  My dad cooks constantly and my mom cleans constantly.

We learned that postpartum mom runs on a hormone that allows us to run like super moms, feeding our newborns every 2-3 hours.  If that's the case, what are my parents running on?
