Yes, I do work on weekends, and trust it is really difficult when your kid is also at home and vying for your attention. And if your husband too has weekends off then it is an achievement to work on weekends.
I try to finish my work when my kid sleeps in the afternoon or I wake up early to do as much work as possible. Or, I do my work when it is my child's time to watch television. I do not compromise on the time that my daughter and I spend together.
