Sleeping issues

My three-year old son woke me up last night.
- "Go to sleep, it's four o'clock in the morning", I said.
- "I can't sleep".
- "Well, then you need to lay down and count sheep or something".
- "I can't count, daddy!".

Which is true... He can only count to three and how many people get sleepy over only three sheep? Maybe he could count those same sheeps over and over again though?

To conclude, he got some hot chocolate instead and that worked well; he was sleeping again within minutes.
