My 13 month old has started head butting things when she doesn't get what she wants or when she's tired. Should I be concerned about this?
My first child used to do this too and it was often due to frustration when he couldn't communicate his needs. You could try acknowledging your daughter's upset and labelling her feelings. Something like 'I understand you are upset. We've had so much fun at the park but it is time to leave now. We can come back tomorrow.'
