S.,
I don't have the name of a counselor or therapist but I do have a recommendation. I know that you say that your daughter has been having panic attacks around other children and babies. Perhaps having a regular playdate with someone would help. Sometimes in life we have to face fears to get over them. Sometimes we need to help our children face their fears and anxieties.
If you are in need of another mom that would understand what your daughter is going through and would be willing to put up with it, let me know. You can email me at ____@____.com. I too live near the Waterfront (in the Greenfield area). My youngest is 11 months old. (I also have a 4 year old and an 8 1/2 year old). If you would like to try to get together for a playdate sometime, let me know.
Sometimes a little time when you don't have to deal with your child's anxiety alone and can vent to another mom can help enormously. Email me if you would like to try.
Hope this helps. Good luck.
