rock a bye baby = baby death

okay, I have a bone to pick with nursery rymes. They always have something crude and/or deadly. For example, rock a bye baby. If you go through the lyrics, you notice that there's a baby in a cradle on a branch. Then, the branch breaks and the baby falls. Which leads to the baby dieing. So, in that case, the person who makes nursury rymes is a sicko. Tell your friends and so on.
