You will love your children, no matter what;meaning, you don't need to feel guilty because you aren't able to do field trips..you will attend the most important ones, like school plays and graduation!
Your children will understand;further, what you are teaching your children from RSD in the family is: patience, compassion, being a good person, strength, independence. I could go on and on,however, I am sure you get my drift.
I have a 21 yr old son; RSD entered the family about 2 yrs and 3 months ago. I did all the field trips that you feel guilty that you can't attend. I was the homeroom mom through 6th grade. Believe me, your children will go through developmental stages where you won't even know WHO this child is..so don't fret.
My son turned out to be a good person.He does bring up to me that I did everything for him, and now he has to learn to do things on his own. He has lived on his own for 1 1/2 yrs. See, can't win,LOL!
