3 yr. old constanly full of bruises

My 3 year old daughter is ALWAYS full of bruises. each leg will always have 10-15 little brusies, her thighs and arms have at least 1-2 bruises on them daily and lately her back has been full of them. and these ones are not little they are big bruises. the other morning i noticed that starting at the top of her left shoulder she had a big bruise and then 4 medium sized bruises led in a line down her back, and at the very top of her behind was a red mark. the next day that red mark turned into another cluster of bruises. otherwise my daughter is healhy has a horse, she eats well, has a ton of energy and does everything a 3 year old will do. as of right now i am a stay at home mom so i know she is not being mistreated by anyone, she does fall alot when she gets hyper and  is all over the place but i do not know how she got the bruises on her back. i am wondering if she isnt getting enough iron, or what could it be? is it normal for kids to bruise so easy?

von Willebrand disease maybe?  Does she have frequent nosebleeds often?

Google von Willebrand.  It's a disorder that causes the blood to not clot very quickly,  so little injuries turn into bigger bruises than you expect.  As I understand it,  it's treatable my medication.

Your doughter may have Nutritional deficiencies especially Vitamin C, Zink, Vit K, Vit E, Vit D, and iron and maybe calcium / magnesium.
My son was very picky eater 25 years ago and he was deficient in all of these Vitamins and minerals and had bruises all over his legs and arms.  You can buy multivitamin in the Natural Food stre without sugar and other chemical additives  and just give it to your child after breakfast.You will se tremendous difference. The first week I gave him multivitamin he was fine and beaming with health.
Hope this helps.

vitamin k deficiency would explain bruising. try a lot of carrots and some form of multivit with vit k
