Oh my, you are really frazzled! I know you are just dead tired, right? And no one gives you any advice worth a dime. I hate those parents, or even worse, people who doen't even have kids, who have no experience with colic who give advice. COLIC SUCKS!!! And that vacuum or dryer crap never worked. Sometimes driving around in the car did, but let's face it, I was so zonked that I probably shouldn't have been cruising around in the dead of night. My son had it for about a month, which is nothing compared to your misery, I know. I don't have any magic cure except to say that one day, it just was over. I don't know how or why, but it was. But before that, we took turns staying up with him, my mom had to come down because we were going crazy without sleep. It was so bad and exhausting and I know just what you mean about the shotgun.
Seems like Eli has had colic for a really long time. Is it just me or is that true? Everything I read when my son had it said it lasted for about 4-6 weeks, but maybe each kid is different? Have you asked his dr or whoever was helping with the GI stuff?
On a lighter note, my dad kept suggesting "whiskey nipples", meaning dip a pacifier in whiskey & then giving it to baby as a colic cure(similiar to gripe water). I never did it, but the name sounded like a bad stripper name and struck me as pretty dang hiliarious at about 3 am when he first made the suggestion.
I hope things get improve and I wish I had better advice for you. Maybe you can find a friend willing to come over for at least one night some you can get a full nights rest? Or get a family member to visit so you & your husband can get some sleep or away time? I bet you could really use it. Hang in there & let us know how things go,
