Just a rant. One of my (lovely) collegues decided to tell me an anecdote today about how they think allergies are on the increase because we keep our children too clean and wrapped up in cotton wool compared to how they use to be.
Great FFS so now it's my fault. 
BTW it's not true I routinely chucked DS outside in the garden to eat plants and worms - he still has severe hayfever.
