My son was born with a mild case of chicken pox. My oldest son was in daycare with kids that had chicken pox and I would drop him off and pick him up everyday but he never caught it. Apparently, I caught a mild case and did not know it. When I went into labor it passed on to my unborn son and he contracted a mild case of it. He had to stay in the hospital for 10 days on medication. He is now 12 years old and has never contracted it again. I had never had it as a child either.
