My 2.5 yo daughters legs bruise a lot from the knees down. the bruises seem to last a couple weeks. is this normal? no bruising anywhere else

Probably Normal: At this age if she is otherwise healthy, this represents normal wear and tear.If you watch carefully, toddlers commonly bang their shins all the time.

Expected patterns: We expect mobile kids to have occasional bruising from the knee down and outside of the elbows overlying bony prominences. Bruises over soft body parts not explained by a fall or other event would be worrisome.
