I have learnt to offer C at the RIGHT TIME when we're fighting over A & B.
My 2-yr-old has been Ms Contrary for past few days. Today she refused to nap. She was so tired by 7+pm, that she was dozing off at the dinner table. She wanted to sleep in our bed. I didn't want to set the precedent cos we really dont want to co-sleep with her. In any case, her crib is in our bedroom. After a short tantrum, I offered C (brush teeth), she agreed. I quickly plonked her in the toilet. There, she said she was tired & didn't want to brush teeth. I offered her crib. She chose to brush teeth again. haha. After that, she just went to bed in her crib.
My hubby took a video of her dozing at dinner. Going to use that to remind her to take her naps.
