No Sleep

I had always thought that when it came to being a parent, you would go through certain stages and then move past those stages. Unfortunately, that is not true of my boy and sleeping. Just about the time he started to sleep through the night, waking only once to eat, he reverted back to waking up twice, then 3 times. I know the 3 times can't possibly mean that he's hungry every time. Matt and I have gotten so little sleep it's comparable to the early weeks. We think it might be him teething again. But I would just like to say that it's not fair...we've already passed this stage...isn't the sleeping thing supposed to get better????
