I've tried to teach Ethan and Grant that I'm okay with them playing/having fun, etc. I only have 2 rules!
#1: We only have out one type of thing at a time (cars, trains, a game, etc)--so we put it away before getting another out
#2: We don't make a bigger mess than we can pick up on our own (or they can pick up on their own--without needing mom or dad to do all the pick up)
These aren't really that hard of rules, right? Just trying to teach them responsibility and caring for our home and the things in it (toys, couches, etc). And for Ethan these rules are very similar to ones at preschool--they can only have one job out at a time (in Montessori schools kids choose what they will work on--the job--and work individually or with a partner...getting it off the shelf, doing it, then putting it away, before doing another) AND they have to have had a lesson on the work before hand so they know how to do it and how to put it away (I equated that to you've never had a lesson/don't know how to, for example, put sheets on your bed--so that shouldn't be something you "play" with).
However, if you know my boys (or read my blog) you know my boys are mess-maker extraordinaires. And despite my "rules" this was one of their latest endeavors-
And to accomplish it meant they had to empty out Ethan's closet! Yeah, not the kind of mess a 5 and 2 year old know how to pick up on their own--although they did bring me the hangers from Grant's room and hand me the clothes off the floor.
We're still working on that following the rules and easy going mom goal!
