Doing home childcare, and the nature of the small group and anonymity thing, I always worried it wouldn't go over big...that in a formal questionnaire format or conference setting they wouldn't be super honest with me about little (or big??) things so as not to make anything awkward from then out?? I know several providers who started something like that and had the awkward thing...
Like a parent brought up a particular item..say, wanting a project brought home every day..or X amount of times a week...or a daily chart each day (many I know do for babies/toddlers up till 18 mos or 2 years old, but not for older kids...many post one singular menu/"we did this today" sort of thing on a bulletin board, or simply TALK to the 3-5 families at days end about it)...but when a parent brought it up, they expected that change would occur. When that was not the point of the providers conferencing/feedback sessions (to definitely make changes occur simply due to parent requests)..so when it was not a change that was made, the parent was mad??
I do know one provider who did one of those online surveys you can create and email to specific people...survery-monkey or something like that? She loved that option...anonymous and all that by the parents (altho, again, with the small group, you can "figure" some things out??). With our relicensing, the county randomly sends surveys to a few of our parents..we can request those results. I never have. Sometimes they have them back before they do our visits. I had a licensor share a few comments once..things like "I have noticed the pan handles not turned in to the middle"...stuff like that, but that was about it?? Helpful..but not life changing as my kitchen is gated off when I cook...LOL. Does your state/county do this?
Personally my approach is to always be talking with parents...make sure they know they can ask me about stuff...like my now well loved and used potty training method...a parent brought this approach to me, we discussed it and gave it a shot! Now its my tried and true method I live by and LOVE (and formerly I hated potty training with every fiber of my being..LOL). I will share info with parents on topics I had training on and ask their opinions, offer articles...and always asking about curricula stuff (want more?, do they think its a good approach with them, should we try this, do that, change it up, etc).
I think for me I try to ride that fine line with "its a business"...and "my business is of a very personal nature".....you get involved in families and their lives to a certain degree...and come to love their children. Open communication and trust is such a huge part of that I guess..so for me most of this feedback stuff occurs in everyday conversations. Its what works for me....
