Hoping for some reassurance here - DS is 13 months old, and I fear is developing my short temper! He is easily frustrated and often bangs his head against a wall (or any hard surface really) if he can't do something or doesn't get what he wants. I try to minimise/avoid situations I know frustrate him but this past week he's been banging his head ALL day, I swear the other day he would have hit it at least 100 times - he has bruises on his forehead!!! He's getting molars at the moment and not sleeping well so I'm hoping it's just that he's extra tired and feeling unwell but has anyone else experienced this? I don't really know how to deal with it other than to remove him from the situation, if I ignore it he keeps banging his head. I'm attributing it to frustration but I have to admit I am concerned it could be a sign of something else...

Any advice would be appreciated,
TIA,
Lise
