Tired Mommy!

(I ran across this picture while looking for a good one of Bauerman sleeping and brought back a flood of feelings from Bauer's first couple weeks of life~ I can't believe how much he's changed in 4 short months!!! so precious!)

Let me preface this little post by saying that Bauer man is such a good baby! He's even becoming easier lately-- he sleeps super good in his carseat while I run in and out of HomeDepot, CFM and Miller Paint. He's been loving this little mat thing my mom has that has the toys over it. Yesterday he even fell asleep just laying there. But he's still not sleeping very good at night.
He'll usually go 3 or 4 hours til 2am, then it's anywhere from 30 min. to 2 hours after that. When he goes 3 hours he wakes up and has a good eating-- if he's hungry, I'm OK with it-- being a month early, I'm so glad he's growing-- but lately he hasn't been really eating very good when he wakes up; instead he smiles, laughs, and talks to me--VERY CUTE but it's not helping my lack of sleep problem. My tiredness has slowly turned to exhaustion and with the stresses of buying and remodeling this house, Andrew's long hours and other everyday stresses. It especially bothers me because as hard as I try, it's effecting the type of wife I am being. Andrew is super patient with me, but I find myself a little more short tempered, a little more sensitive, and a little more naggy (or A lot of all of those things...) I don't want to be that wife and Andrew sure as heck doesn't deserve it!
I've read most of Good Sleep Habits, Happy Baby and liked it-- Bauer's taking better naps in his crib during the day and he goes to bed around 7. I don't have trouble getting him to sleep really...
I don't really know what advice I am looking for...or maybe none at all. I know every baby is different and some just don't sleep fantastic (Bauer sure has many other endearing qualities!!) Some ladies I got together with from my ward on Friday night were talking about BabyWise-- i had never heard of it, but thought maybe some of you (or the 3 of you that look at my blog) may have. I heard it's a little intense, but would you recommend it? what parts did you find particularly helpful? I've started to let him cry it out a little here and there (i was hesitant to do so before now since he had the crying/breathing issues at the beginning) and I'm not opposed to it if that's the training that works best, but I just want to make sure I'm following a plan and doing it right if I'm going to start it.
Maybe my answer is just-- your a mom now, get use to it...and if that's the price I pay for having the extreme pleasure and blessing of being Bauer's mom, than I wouldn't trade it for ANYTHING-- not even a full or even half night's sleep!
