Finding special time for my daughter

I schedule twice a week swimming and ballet for my daughter. My husband comes home from work and stays with Andy, so that I can take her to her classes. It has been hard to keep my daughter from being jealous from all the time that Andy requires. So, this gives us special time together. I am also having a hard time keeping her busy during Andy's therapy visits. It is best if she is in school, or doesn't have to go with us, but lately she does. She can only color for so long, before getting bored. We may have to invest in a DS or something. Ipod works for a little while, but she is only three. Next year, I will try to better get her school days coordinated with his office visits.
