Things I've learned the hard way: 1) Always check a Pull-up before you pull it down. 2) Ovens are hot mirrors and children are apparently parakeets. 3) Ice cream will inevitably end in tears. 4) A puppy will not be easy just because now you've taken care of an actual baby. 5) Sex is almost impossible and ultimately ends in more children.
Words of wisdom for the day friends and future mommies, and Ya, Ma, I know, you told me so.
