I have a 3.8 year old DD and 2 year DS - we have some days when we watch no TV (and therefore feel like a very good and proactive parent but get no chores done at all) or on other days I have alarmingly realised up to three hours when added up (if I were to be totally honest I am a little concerned it may be more!). It adds up quite quickly - if watched in short bits! Just wondered what others do?
