Dear K R, It sure sounds like you have your hands full girl. I'm not a doctor, just a mother of two lovely daughters. I wouldn't worry about the cough unless it stays longer than two weeks. It's possible that it's an allergy, but I don't think so. Only because if the baby's allergic to the dogs you would have seen signs before now, more than likely. I like a wet cough better than a dry one. Is it a productive cough? Is he coughing anything up? If the cough lasts longer than a week or two I would take him into see the ped. I did just read an artical on line last night about children and coughs. It stated that at night time, if you put Vick's Vapor Rub on a child feet and then put socks on them, 100% of the time the cough will stop! (I have not tried this, as I said, I just read it last night.) It could be worth a try. I've heard of sillier things that have worked! Always remember that the doctor is a call away. You could just speak with a nurse and get her advice. When it comes to health, nothing is better than a pro!
I hope you get another job soon. One that would give you some well deserved time off, not to just clean, but to give you a break. Best of luck and happy new years.
