Have had the same problem here...but it started a little earlier. 3-ish
What we did:
1) We got rid of his dresser
2) We got rid of hangers
....neither in a negative/punitive way....
3) We got the brushed nickle, rounded hooks they sell in bins at Home Depot. Color I'm sure is irrelevant, the point really is that they weren't pre-mounted on a bar and they had no sharp edges. They're in the drawer knob sections and cost about a buck each. I think they're for posh kitchen towels. Much smaller then normal clothes hooks and much larger then the kind that's half hook/half screw.
4) We measured (by holding a pair of his pants up to the wall and giving it an extra couple inches for growth for the lower row, and held shirts up so they'd drape an inch or 2 over the pants for the higher row) marked, and used the electric screwdriver to mount them. Thank god. I'm talking about 35 hooks here, each mounted with 2 screws.
5) We hung up all of his shirts on the top row, and pants on the bottom row. (Telegraphed that punch, didn't I?)
6) We bought a colorful, see through, 3 drawer plastic filing cabinet from OfficeDepot and placed in beside the rows of hooks.
- One drawer = underpants
- One drawer = socks
- One drawer = pjs
RESULT :
- He could see all of his clothes options (we changed them with the seasons) at his own height & level.
- He could wear whatever he wanted. (I did actually make an effort to buys clothes that would all mix and match over the past 2 years...this year we've branched out...with some interesting results).
- He also became responsible for putting all of his own clean laundry away. Easy, peasey, hang them on a hook direct from the dryer. No folding or hanger-wrangling required. This was one of his Big Boy jobs. Now, of course, 2 and half years later its just a chore....but boy was he proud of his work for that first year.
- Within a week he was picking out his own clothes and dressing himself.
***Also*** On the advice of his preschool teacher, if he threw a fit in the morning, No Big Deal. Into the carseat, out the door in PJs. We'd keep one extra set of clothes bagged by the door. The peer pressure of being in pajamas, with a bag of clothes in hand, when EVERYONE ELSE was dressed meant a quick change. That happened 2 or 3 times in the first year & never since, and only one time did he not insist on changing in the car. I don't know if yours in in school, or if your teacher would be down with that, but it was the nail in the coffin on the clothing issue for us.
The whole attitude we took over this period was the same as some of the other posters have said: No Big Deal, Not Worth Noticing...&....Hey, you're big enough now that this is what we're going to do (and drop it).
