late night

Alright, so we seemed to have gotten the naps figured out, all until our trip to Boston, and now we are having a bit of trouble. Kix was doing great! He was napping a couple times a day for a few hours and sleeping through the nights off and on, but he would always go right back to sleep after waking up to eat if he didn't make it all night without a snack. However.........we took a trip to Boston for a week during this time he slept great at night, but most of his napping was done while wearing him around town or on the plane in my moby wrap. Since we have been back home a total of five days now, he is slowing not wanting to nap if he isn't being held. And tonight he is not sleeping. It is currently 4:31am and I am letting him cry it out, he's been crying for 15 min now. Its not a constant mad cry yet, I will see how long this can or will go on. So far I'm doing ok, deciding to blog while I listen to the sad sound of my baby crying. But he must learn that he cannot be held to fall alseep, he must sleep on his own.
My greatest frustration lies in my day ahead, I have some family heading my way tomorrow, sometime in the morning might I add. And I was planning to go grocery shopping before they arrived, this I may do, but going on little sleep, so far 1hr 45 min! In addition to my lack of sleep, I'm afraid Kix may feel that he will not nap, so my delimma, do I try to make it peaceful for them and hold him while he naps or make it easier on myself and continue training him to sleep on his own and let him cry for who knows how long???
I need to pray and pray the Lord can only help me through this. I will now go to make my husbands lunch as he will be leaving for work in a couple of hours..........
