usually not. you can just use soap and water and clean it really well put a band aid on it and you should be okay. if you want to use something like neosporin or a triple antibiotic ointment it's okay it will help prevent it and maybe if your child is very active or plays in sports you may want to put a little bit on the bruise or cut that they have before they go out and play. but other than that soap and water really does the trick.
do minor cuts and scrapes on kids need an antibiotic ointment?
