They may want to give the kids a chance to get acquainted better.
I know that my mom was thrilled anytime I showed signs of getting along with nice, civilized,alpha females.
I think she hoped some of their virtues would rub off on me.
Otherwise,the older girls I looked up to were taken from the media.(Mrs.Peel,Nyssa,Janis Joplin,Joan Baez,Catwoman and the Black Widow),the social activist movement,(The Farm and the Highlander Folk School) and the assorted female barrel racers,long haul truckers and pole dancers I made friends with.
I think Mom preferred I grow up to be more like my buddy Diane who was an artist,musician, fibre arts genius ,critter addict ,linguist,historian and science fair winner and a wee bit less like my friend Sandra who could spit four feet between her front teeth,
shoe a horse by herself and rebuild a Chevy Malibu.
That sounds a bit snobby but then I was picked by parents to be a role model for younger girls whose sisters and neighbors had had 4 or more husbands by the time they were 19.

IF Madison enjoys these children's company,go for it.
She'll have friends,the kids will have a friend their parents like and maybe you adults can bond,too.
The trickier part will be when your kids are sought out by less-than-perfect youngsters.
Few people want their offspring with the 'wrong crowd' but the kids who might wind up
kicked to the curb need all the contact with the 'right crowd' they can get.
I think you'll have a hard time dealing with never letting your kids go over to so-and so's
house or riding with what's-his-name's parents while you have them over and run them around all the time.
But you can't allow these matters to be reciprocal if it's not safe.
Congratulations on having high standards for your kids and beaucoup congrats for having
the kind of child that others are attracted to and want around their home and family.
You done good,girlfriend!
