Call me an assertive bitch but I would do just that - come upstairs and say to the children in my ice but firm voice "x and y you need to stop now - at Reggios house you know we do not run around with boots on cause babies crawl on these floors plus you could hurt yourself - the rule at my house at dressing time is you sit on your bum on the bench until everyone is ready to go outside and when the grown tells you than you can get up. You need to listen to mommy at pick up or you will have to stop playing before mommy comes and Reggio will have you sitting on the bench ready to go for mommy at pick until you can show us you are ready to listen and respect mommy and follow my house rules!"

And I have done that ... had everyone upstairs for pick up time doing quiet activities at the kitchen table with two of my wild sibling set sitting all dressed on the step for thier parent cause they are missing out on the fun we are having at table - when parent comes they get shooed out the door and I do that a couple days and when they go home gracefully we try again with parent attempting to pick up - if it devolved again I say to the parent the next time - this is not acceptable behavior in my home and I cannot keep having them ready for you to avoid this cause it is not fair to the kids - you cannot allow them to dispresect my home or you this way.

Honestly do not care how they behave outside my home or now people want to parent at home as long as it does not affect ME cause while in my house or on my property where my charges can see and hear you or where I am going to potentially be liable for an accident or injury - you follow MY HOUSE RULES ... and it is my right to enforce those whether your are 2 feet tall or 6 feet tall

You not liking that you go do business elsewhere!!!

Seriously not allowing non parenting in my home - nope nope nope - cuase it is like a virus - kids see little Johnny acting like that and getting away with it and them they try it too and before you know it you have pick up or drop off mayhem!

Children are competent capable individuals - they generally want to behave and please impress adults - even my 11 month old is sitting at the cubbies waiting now cause I would allow him to try to sit with the bigger kids - if he crawled away he went back on his booster seat with a quiet but firm "we sit on bums and wait for friends" ...he would cry in the booster cause he wanted to be with kids - next day we try again second he starts to move to crawl I do the "ah ah you dont want to go on your chair do you?" he sits back on his bum most days when he did not back in the chair - took a week to "get it" ... sadly he sits better now than my one 4 year old who I often have to redirect to focus and get dressed

My long winded point is this is your home you do not have to allow mayhem in it??
