To think my nearly five year old should be able to wait

[canyouwait]

This is really starting to grate and I wonder if I am overreacting.

So obviously sometimes I’m doing something else and I need my ds to wait. But he just ignores me.

So something like
’mummy?’
’just wait a minute DS’
’MUMMY?’

It is just so wearing.

My parents never, ever responded to any banging on or shouting through bathroom doors, and would claim afterwards they couldn't hear me. Genuinely believed the bathroom door was soundproof until I was about ten.
