I know this is a common thing that some toddlers do to express frustration etc.
But DP keeps punishing my 21 month old DS for banging his head when he's upset by putting him in his cot for a few minutes. He tells him not to bang his head, and when/if he does it again he puts him in his cot.
I feel really uncomfortable about this because I don't think head banging is necessarily bad behaviour, just frustration for not being understood. Therefore making the situation worse when he gets shoved in his cot.
I can't stand hearing the crying  and there's no reasoning with DP about it... Thoughts?
