Pray and go with what you feel in your gut... go with your instincts, trust them. (((Hugs)))
It's okay to put yourself first in this equation. If you cancel plans, if you go forward with them, whatever is best for YOU is truly what's healthiest for your child.
Kids are resilient and it's okay for them to not like our decisions. We don't have the right to change or manipulate their feelings. We do have every right to keep them in safe environments. Sometimes that can include an ill parent. Sometimes it doesn't.
May you have a very merry Christmas, however the plans shake out!
