I think having a special child of our own makes us be even more empathetic to what others may be going through. Do all you can WITHIN your ability to do so but I would never let it compromise what I am already doing for my own children. I would love to help a lot of people but sometimes I cannot help myself or my children and so I have to resolve to knowing I could only wish to do so. I guess what I am saying is do not feel guilty but there is nothing wrong with establishing communication with others who may just need to know someone is thinking about them.
More opinions appreciated on trying to help others as a parent of special needs children should be elaborated promptly so as to find trying to help others conceive and maybe get a better idea.
