Chicken Pox in babies?

Go see if you can get him vaccinated. It will lessen the symptoms, it is actually recommended that after exposure a child over 12 months be vaccinated within 24 hours, but it may still help now. The younger they are the less sever it is, but since he would've been due to receive the shot in a month anyway, I would just go see if you can get it now. Call the nurse's line or the CDC vaccination hotline they will be able to tell you if he's still eligible to receive the shot now or if it's too late.
