I have not used this with my children- I think it's very new- but a friend of mine uses it and has only positive things to say. Normally, I would not give a third person review but becuase this can make a child's life a little more pleasant, I am going to go ahead and share what my friend has to say about this product... It's called Buzzy and apparantly its basically a vibrating ice pack type of thing. Before your child goes for blood draws or immunizations or some other type of shot, you ice the area for less than a minute, then you move it to a different area while the shot is being administered and between the cooling and vibrating stimulation, the pain sensors are thrown off and the whole experience is less difficult on the child (and parent!). He says it is suitible for babies all the way up to age ten or twelve. Like I said, I do not have first hand experience but if it helps even a little, it is worth trying as far as I am concerned. My friend swears by it and I think it would probably make a good baby shower gift! Does anyone have any first hand experience, thoughts or comments about the product?
