As Foreigner sang in 1984, and Mariah Carey then repeated "I Want To Know What Love Is." Yes, it's a many-splendored thing, but definitions don't come easy. For adults, that is.

In honor of Valentine's Day, HuffPost Parents teamed up with Parenting.com to ask them for their best guesses at how to define a highly complex emotion. And though they're under four-feet tall, their ideas of love stack up to be exactly the profound -- and adorable -- Valentine's treat you didn't know you needed.
