Remember, the goal of discipline is to correct, not punish
That weekend I felt she was trying her luck too much because when we were out and while I was busy talking to somebody she would interrupt to ask if she can play a bit more (I set an alarm always to see to it she hands back my phone when she’s consumed her time). Out of convenience I simply and repeatedly said, “Okay, okay 10 more minutes…” But of course, it was not just 10, it was 10 minutes x 6 and more. What’s more was that when we got home she told me that she has not yet watched the videos she really wanted. I took it as a go signal that I needed to intervene and call her attention about getting her way and obeying Mommy and not taking advantage of situations to ask for permission nor extensions.
