Cold easy** not child sorry, stupid auto correct
If you bruise that easy you may be anemic and have an iron deficiency. If that's the case you my also get child easy and are a heavy bleeder when you get cut, I would talk to your doctor and have him run some simple blood tests to see if this is in fact the case. If so you can buy some iron pills at any pharmacy store (cvs, walmart, wallgreens) and it will help with the problem
Hope this helped and remember to hope for the best but expect the worst.
