Parenting lessons that many parents had to learn the hard way:
  1. Super glue has no place in a house with young children.
  2. Neither do Sharpie's. 
  3. There is no such thing as allowing your kid to play with your phone "just once."
  4. Don't use Google to diagnose illnesses. Ever.
  5. Always carry wipes, long after diaper wearing has ended.
  6. Keep track of who gave what at birthday parties.
  7. Never stock batteries in your house, or you will be forced to make obnoxiously loud toys work once again.
  8. Backup all photos. Better yet, print them.
  9. Look in the oven before you turn it on.
