Irritated...

My 15 month old still doesn't sleep through the night but this doesn't bother too much since I just stick my boob in his mouth and go back to sleep. And besides, his almost 4 year old brother was the same until he turned 2.5 and now he sleeps through night just fine.

What does bother me is that my 15 month old recently started waking up before 6am and nothing I do puts him back to sleep. I am definitely not a morning person and getting up before 6am is putting me in such a sh** mood. And on top of that, his 2 day naps are getting shorter and shorter (I'm lucky if he naps for a total of 1.5 hours between 2 naps). I won't do cry it out (makes me feel bad) so I am at a loss at what to do.

Any idea why he recently started waking up before 6am? Could it be a growth spurt? Teething?
