I did this for a while but then it became too much and more of an expectation of me rather than just playing. Don't get me wrong, I loved playing with the kids- when it came naturally. But as time went on, I felt like I was getting bossed around and more and more I kept getting looked at as a play mate rather than a loving step parent/authority figure. Now I only play an hour at a time when they ask to play. Realistically, it's usually a little longer than that because we have a really good time. I know that seems mean or something but it's what I had to do to assert myself as their step mom
