I think that age range is way too wide. The 10 yr olds are in a different place maturity wise to be in a group with 18 yr olds. Many 18 yr olds would not be interested.
It is not something we would be interested in, especially with a group of women we don't know.
I do feel strongly that it is important to have special bonding time with children. Over the years, we have done a lot of activities which promote bonding......mani/Pedi's, spa day, shopping, lunches, workout, etc. It is something that we incorporate regularly into our schedules.
Now that my daughter is 19 and moved out to her condo about 20 minutes from me, we make a point to do lunch at least once a week with a little shopping or we meet and workout together.
We are texting queens and we keep our phones hot texting each other all the time.
ETA: We've also done mom/daughter trips to NY and FL
