daughter stated coughing right after her b-day party. My hu*****and said it was viral. She got much better in two days. Did you ask your pediatrician about giving multivitamins to your kid? Consult with them first.
Also, I am applying for pre-school for my daughter too. I can't wait for her to start. It will be a big step forward for the kid and parents. I m sure she will get sick periodically. But it is how ids build up their immune system. Relax and enjoy the holidays.
