Parents say the darndest things

Here are some reasonable and logical arguments that nevertheless somehow fail to make an impression on 3-month-old children:

1. You're so tired, you should go to sleep.
2. I'm so tired, you should go to sleep.
3. It's really late, you should go to sleep.
4. It's really early, you should go to sleep.
5. You're so upset, you should calm down.
6. You can't possibly be hungry, you just ate.
7. Your nappy can't possibly be dirty, I just changed it.
