My kids did well in school this year, and all I did was say "congratulations." I get the feeling they want something more tangible, meaning, gifts.
My 17-year-old hinted that her FRIENDS were getting presents for their straight As. I knew what she was getting at, but I did not take the bait.
My kids went to Montessori pre-schools, which encourage love of learning for its own sake, not for a reward. I embraced this philosophy and have tried to reinforce it in my house.
I see parents carrying presents or flowers at awards ceremonies and wonder if I should do the same. I know my kids would appreciate it, but I feel like it would go against the ideas I am trying to instill. Still, I wonder if I am denying them a pleasure they deserve for their hard work.
