Okay... I have had play-dates for my kids, since my eldest was in Preschool.
I am casual about it and so are my friends.
It ALSO depends on the age of the kids and their disposition.
I have personally, NEVER 'expected' the "Host" to be super spot-on or involved... in being a Mary-Poppins. NOR to be a 'more involved' parent... than I am. It is her home... and I do NOT expect the Host... to be entertaining the ENTIRE play-date. How exhausting... and she is not a school Teacher, nor do I expect her... to be one, on play-date.
Bear in mind, that the play-dates "I" host... are ALSO for us Moms, to have our time too.... and 'adult' interaction. My friends, are the same way.
I hold no higher expectations for the Host.... other than just appreciating that we were invited over, and I KNOW she is doing what she can....
For younger kids, they do need more hands-on supervision and direct activity... .with older kids, you do not.
Moms... can gauge their children, too, and others.
When kids come to my house... we have a LOT of toys, and crafts and an outdoor yard and yard apparatuses. So they do that... and they play nicely... I also serve snacks or a 'meal' depending what time the play-date is.
BUT... the visiting Moms... ALSO, on their own... bring food/snacks for the kids and activities, from their home. It is... the way it is... here. Culturally and custom. The Moms (and if the children are old enough), ALSO help to neaten up and clean-up.... before going home.
My play-dates... range about 4 hours.
And NEVER.... held at a nap time, for my kids.
So, mornings, are always when I have my play-dates, at my home. AND I always state a start time and end time.
My kids, are always very independent and so are their friends. They as a whole... are just fine with my having a little directed activities... OR them just hanging out and playing on their own.
It is fine.
A play-date... should not be, cumbersome... nor a pain for the visitors or the Host.
And the host should NOT be expected, to be Martha Stewart.
all the best,
Susan
