15mo self harming!

Amanda • Mommy of 1, 1 heaven baby, 1 on the way.

Ugh so my DS is slamming his head into the floor and into other people when he is mad. Today we had a doc appointment and since we missed nap time he was so tired and crying uncontrollably then he starts slamming his head into the floor (it was carpeted) but now he has marks all over his forehead and bruises. Anyone else have this problem and know what to do about it? I fear he may really hurt himself.
