I've found that parents hear you but they don't "listen".

Instead of saying anything or dropping hints that you have things to do or that mom/dad need to get to work, physically take the baby, say "Wave goodbye to mommy! Have a nice day!" and then turn around and walk in the opposite direction.

.....even if that means going to stand in the corner of the living room where the parent can't see you. Walk away.

The parent usually leaves immediately. Rinse and repeat.

I've found my body language actually gets the point across much better and much more clearly than words at times.
