DS's 19 months, so I might just be expecting to much but he has decided me saying no means he should continue what he's doing whilst repeating the word. For example:
Lying in bed waiting for him to go to sleep
DS - kicking me whilst singing "kicking, kicking, kicking"
Me - "Don't kick, mummy doesn't like that"
DS - stops, looks at me then starts again
Me - "DS. No kicking" (didn't raise voice, but tried for a stern tone)
DS - "no kicking, no kicking" whilst laughing and continuing to kick
I try not to shout, as I don't want him to be afraid of me, and at this age I don't feel any form of punishment / consequence is appropriate, So I'm not really sure what I can do.
He knows what no means and says it in context so I think he's just trying to push boundaries, but I'm at a loss about how to respond.
