Should I be surprised I want a football team?
"As you hold, rock, or nurse your baby, each of you gets a rush of dopamine, the main currency of pleasure in the brain. While you're both enjoying the high, your baby's feelings for you are taking root. Again, animal studies give us an important insight into human love. In 2004, Italian researchers reported that baby mice that couldn't sense dopamine didn't especially care whether or not their mom was around, the strongest evidence yet that dopamine plays a crucial role in mother/infant bonding. Incidentally, dopamine is the same compound that "rewards" users of heroin or cocaine. In a very real sense, addicts who get hooked on drugs are simply chasing the feeling that flows between a mother and her baby. Parental love just happens to be infinitely healthier." -Babycenter Bulletin
