My eldest 2 had chicken pox when they were 4. The first one was pretty much ok but the second one was very itchy and feverish for a week. It wasn't pleasant for him (or me!). Once my third child got to 4.5 without any signs of having it I decided to have her vaccinated. I had chicken pox when I was 7 or 8 and was very ill for a week or two, and I didn't want her to go through that.
I had her vaccinated at the private GP on Bellevue Road as our NHS GP wouldn't do it. I believe the practice on Bellevue is now called the Smart Clinic. She was vaccinated 3 years ago and I still haven't arranged for her to have a booster, partly because I understand that even if she gets chicken pox now it will just be mild, which is all I was really trying to achieve anyway. I hope this is true!
These threads always remind me that maybe I should get the booster done, if anyone has more information about this that would be helpful
(BTW I think it is really unhelpful to point out that "my kids were fine so what's the problem?"
, for some children it's really not fine)
