No offense intended at all, but I think I expect more willingness to tidy from 2 year olds than 5 year olds. That's certainly how it's gone down with my 5 year old, and now my toddler is loving the heck out of cleaning, too.
My DD5 is extremely willing to help me and do me favors, but not very willing to clean up after herself. She finds her own messes very overwhelming and needs very clear instruction on how to clean up.
At the moment I expect her to
- put her dirty clothes in the basket right away
- put her outdoor clothes on hooks/shoe rack and put her backpack away after school
- clear her place and scrape her plate after meals
- clear her art supplies and toys from the table before dinner
- tidy up her room before bedtime. This is where she really needs help. I stay with her and give her categories to deal with. We always start with the same two: clothes and books, then doll stuff, dress up, and so on. If I don't do this, she flip flops around like a fish wailing and screaming "I can't! I don't know how! I'll NEVER be able to do it! Agggghh!" And I just can't deal with that at bedtime
Other than that, I do ask her to do specific small tasks often throughout the day, and she always helps clean up if she makes a big mess, like a spill.
So I think if I was to whittle down my advice I'd say to
1. Make the easy things part of the routine
2. Let her do jobs that make her feel important and helpful
3. Break things down into small, specific, doable tidbits
