Worst. Night. Ever.

Again, I am sitting to type a post about Jackson and his horrific sleeping. It is getting unbearable for both of us; for me because I am so tired I feel that I am not being as good of a mother to him, and for him because he is not getting near the amount of sleep he should be getting. He woke up last night at 11:30 and I let him cry for an hour...I am not an advocate of crying it out, however I have run out of options. It was not even worth it, because he still did not quit crying. I rocked him to sleep and the minute I put him down he started screaming again. This went on until 2:00 am and finally I gave in and put him in bed with me. Of course, he slept like a rock until 7:00 this morning. And as we speak, he is screaming and I have already gone in 2 times to comfort him. I don't know what to do. I thought it was teething at first, but I know now that he knows that I will come get him and he is learning how to work his mommy already. I feel so horrible listening to his cries, it makes me sick to my stomach, but I don't know what else to do. He is also back to only taking two 30 minute naps a day which also started when he started screaming at night. I am wondering if it is now time to drop his morning nap. I have no clue...just when I thought I had if figured out.....
