How likely is it for a 9 month old baby to catch chicken pox?

Only if exposed. Since the onset of the chicken pox vaccine we see much less chickenpox in general. It is therefore less likely for your 9 month old to get it, but if exposed to someone who does have chickenpox it is likely your baby will too.
It's possible... ...But not particularly likely. These days, most people have been vaccinated against it, or had it as children. But if your baby was exposed to someone who had it, he/she can get it. That said, many rashes look like chickenpox to non-experts -- so don't jump to any conclusions. Let your pediatrician or a dermatologist look at the rash to see if it's that or something else.

Can a 6 month old baby get chicken pox?

Sure. Chicken pox starts as small reddish spots, which form a very small fluid-filled blister in the middle of each spot. The small blister breaks easily when rubbed, releasing a tiny drop of clear yellowish fluid. Each spot then forms a small scab. If the mom was immune, her antibodies may protect the baby from age 0-6 months. At age 6-12 months, the baby might not be immune. Can get vaccine at 12mo. Read more...
