NOOOOOOOOOOOOOOOOOO! Never wake the sleeping baby!!! That was rule #2 that DH learnt. Rule #1 was boobs are awesome.

Babies of all ages will throw in extra hours as their body requires. Growth spurts, illness, and I'm sure 'pay back' are all common reasons for long sleeps. But unless you absolutely couldn't miss an appointment/flight/etc, I could never find a good reason to wake Jack. It never worked out well for us when we did wake him.

Although, I SWEAR he would know when I had a playdate or ABA meeting I really wanted to go to, and he demand a sleep, or fall asleep unexpectedly while feeding.
