Co-pays, co-pays, co-pays

Okay, for those of you out there that have more than one child, maybe you can relate.........Why is it that you can go months and months without a doctor's visit and then have to go twice in one week with two different kids???? Ethan has a double ear infection and sinus infection (Co-pay, I mean dr's appt weds.) and Kacey has an ear and eye infection(copay, I mean dr appt today) Seriously, why can't we space this stuff out?????? Thank goodness for antibiotics!!!!
