My daughter's favourite game to play with Banjo is to hide under the doona and then the dog 'digs' her out. It makes me laugh too. But tonight at bedtime my daughter tried to get under the doona 5 times and each time Banjo would grab the edge of the doona and pull it back. It was hard not to laugh, but eventually I had to sternly tell her to stop.
What games or behaviours have you regretted encouraging?
