Pediatricians say parents shouldn't feel bad if their child gets lice or assume they did something wrong – as mentioned, it can happen to anyone. Signs for lice are pretty obvious. A child will typically scratch their head and be unable to stop. You may also notice little white dots in the root of their hair that look like dandruff, but it's actually the lice.
