Fake Cough!!

Has anyone else's kid done this??? But Ben had a fever the other day and he started coughing a lot more then normal...so being Dr.MoM I diagnosed that he was sick (1st cold) Then the next day no fever but still had a cough...no big deal. Then the next day when he was not getting any attention...I heard this cough...but it was not a real cough...it was a fake cough. VERY ANNOYING!!! So...now every time he wants attention or is mad, he coughs. I am trying to ignore it...right this is the best thing to do... at least that's what I think!!
