If you have that conversation at a table, and the two year olds insist that they all need a place at the table and need to be included in that conversation, do you let them?
But another rule I had was never to repeat myself. If I said no, that was it. If whining ensued, they were on ignore just as much as if they were throwing a full blown temper tantrum.
I probably was a tough mom with all my rules - but in my experience kids want attention and they should have it but not as a reward for poor behavior. In fact, I'm sure I was a tough mom - when my daughter would misbehave I'd start counting. I seldom got past three. LOLOL!
