Nina that is so awesome.
Kids pick up and absorb so much more than we give them credit for.
My grand daughter lost both of her grandparents (who lived in the same house with her) when she was 2-3. We knew she was suffering greatly from their loss but at that age there seemed to be so little we could do to help her. How wonderful that you found a program and took them. And since kids are so resilient they do recover quite quickly if we give them a chance to express themselves.
You took a huge step to making sure they will not be seeing a therapist about this 20 years from now
