The joy of discovery - figuring out what makes each stage easier - is half the battle won. And you're right; the little rewards and sticker charts are such a cute way to encourage the tiny tots without having to dole out actual prizes all the time. My experience has been that children at that age love the immediate gratification of stickers stuck everywhere, haha! But yes, as you said, what's worked this week may not work next week - or even tomorrow! I've found that having a repertoire of tricks up my sleeve is helpful because I can then alternate and adapt them according to situations.
