Adhd or Justakid

Documentation of my son's behaviors that concern me.
  1. Bit big sister on the back when she wouldn't play as he told her to. Immediately sorry and apologetic.
  2. Growling at grandpa when he's told to clean up his toys. Bares teeth.
  3. Must be told 5-6 times to put on socks and shoes but is always distracted by something or just refuses to do it. Feels like he's refusing because I've asked him to.
  4. Cannot stop wiggling while eating, either at home or away from home.
  5. When asked to clean up, promises he will but never remembers to.
