Here's a not so secret quality ogf strong famlies. They have fun together.
Playing together as a family lightens the mood, puts a smile on everyone’s face, and creates memories. For stepfamilies the added bonus is it bonds you together. Playing games and having a little fun competition helps to break down walls and connect you. You can read a book together. Learn to play an instrument. Or go on a family hike. Sure there are going to be times when not everyone wants to engage in every activity so find what they do like and take it one day at a time.
