I invariable make my dd who is 4 and half draw a card and write Thank you and her name at the bottom and do send it.
However recently we had a kids party and did not receive a single thank you note. Just the odd text message, but mostly nothing.
What is the norm? I always write a thank you note if I go to dinner or a party at someones house so shouldn't children get into the habit? Am I overdoing it?
