we purchased the thermometer because our son (15 months); Unfortunately we got with a conventional thermometer only trouble with the winding according to the disease; our little one was of course skeptical and there was always a long fanfare until he had forgotten the temperature measurement again; otherwise the Thermoscan - it is not an issue; We measure in a playful way; said measuring is very quick and easy; measure while sleeping is not an issue .... I am very happy about this purchase! I highly recommend this Thermoscan only every Mama / Papa; the price is ok, when you see the result :)
