Recently having a conversation with a fellow school mum who told me that, on the advice of another mum, she has been regularly giving her children a worming treatment 'just in case'. Is this a thing now? I've only heard of giving worming treatments when there is a known case of worms but she does it monthly. Is there any harm in doing this? I don't know what the active ingredients are but could there be harm in putting them into your child on such a regular basis? I've never treated my child for worms, I've never had to, so I was a little shocked that she is treating her kids in the same manner you would your pet dog. What do you think? Have I missed a vital parenting lesson somehow or is she being a bit overcautious?
