Hello.. my baby girl is 8 months old.. She fell forward while sitting and hit the floor.. I immediately called the pediatrician office & they told to observe her for 24 hours..so far she has been the usual nothing worrisome, but this bruise showed up & I'm worried.. any advice or remedy for the bruise? Thank you!
