Hello C.,
I'm B. and am also from Houston, I moved in July to Richardson / North Dallas. I am mom to 3 boys, ages 14, 10 and 8, and have quite a bit of experience with no sleep. =)
It sounds like your baby maybe experiencing some discomfort in his stomach, and if that is so try Mylicon, it's over the counter, and expensive, unfortunately, but it might help. If you can give him a very warm bath, using some kind of chamomile soap and / or lotion after, and then put him into warm footed pj's. Give him the mylicon and a very mild drink of caffeine free tea and mint. This always worked for my boys, and I never had sleeping problems after I tried it.
It may not work for you at all, and you may want to make sure your baby isn't allergic to mint, unless you already know, of course.
Good luck to you, I hope I helped a little.
B.
