Bruising is not uncommon in slightly older children, particularly once they start walking as they tend to fall over frequently. It is usually of a benign cause and we most commonly see frequent bruising in children who are very flexible. Flexible children not only fall frequently but also have very flexible skin. This means that when they get a small bump they will develop a bruise whereas most children need quite a lot of force to induce a bruise. There are, however, other causes for easy bruising such as low levels of platelets which can sometimes happen after a viral illness. Additionally some children have a deficiency in the clotting factors and this can also cause bruising. If there are very tiny bruises 1mm or 2mm in size or other symptoms such as nose bleeding then it is advisable to see your doctor who can do some simple blood tests to check that there is no deficiency of the platelets or clotting factors but mostly easy bruising is innocent due to skin flexibility. Suppleness and flexibility are easy to assess and certainly something that your doctor would be happy to check for.
