Дочь с проблемами со здоровьем: как объяснить это старшим детям и справиться с трудностями?

Im struggling a little, my daughter has a lot of health issues and sometimes its very overwhelming, sometimes my older kids dont understand and i try to make them understand in the easiest way possible. But they just cant they are too young to understand her disabilities. Its frustrating, i know eventually they will notice shes different and that she is not like them, and i try to explain we love her anyways and that we dont treat her any different from anybody else. I try to explain that she needs more care then they do and if they ever feel like they need extra mommy time then they can come and help and hang out with me. Im just having a difficult time. 😕
