My 7yo school going daughter is quite forgetful and can misplace things or cannot remember some of things that happen in school that day. Is this common or should i consider having her seen a doctor?

When I was 7, my mom had my 2 year old brother and a newborn brother, so her hands were full with them and she could not keep an eye on my school work. I was very forgetful at that time too, I kept forgetting to check my notebook and bring the correct textbooks to school. The school teacher had to chat with my mom and after that my mom made it a point to check on me often. I think you may just have to supervise her more closely. After all, young children are still very dependable on their parents.
