My sister fosters children, some of whom have had special needs due to their mothers abusing alcohol and drugs in pregnancy. We have learned so much from these children, not least to allow them as much independency as possible as they grow, no matter how tempting it is to do everything for them. They have dealt with multiple problems and face many more, especially when no adoptive parents can be found. Other children in the family take it all in their stride and the health worries don't concern them, other than they are helpful and sympathetic when a child is poorly. It's eye-opening to watch how medicine and care routines, disrupted sleep, frequent hospital visits and care planning meetings can take up all day and every day.
