sleep ?

Is your LO sleep schedule the same every night? My LO is like clockwork but last night he woke up 2.5 hours earlier. Is this normal to go through different number of hours at night? I'm a FTM and he has always slept 12 hours, if this is normal great, but I just want to make sure it isn't a sign of a sickness coming along. I am probably stressing over nothing, thanks!
