Ugh, need sleep.

So the last few nights little man hasn't slept well. But last night, he went to bed at 8, woke up at 9, woke up at 12 and ate, woke up at 2, then again at 4, then up for the day at 6. It's driving me crazy. He had been doing so good sleeping in his play pen and only waking up 1 time to eat. But his top teeth look like they're about to break through so that could be it.

He has been eating more often, 5oz every 2-3 hours when it was 5oz every 4-5. Is it a growth spurt? He was born on July 2nd and is 5m. SOMEONE HELP ME PLEASE.
