I go through this every year. They get tons of stuff, then get on their computers and completely ignore or refuse to open what they have. A year passes, I give it to good will and they whine that they have nothing to do. Or my favorite is they don't don't mention the item or touch it all year then throw a fit when I said I got rid of it.

We put up all the craft kids or art-related project stuff too. They do those over the course of the year. If left in their rooms, they'd get randomly opened midst normal play time and pieces/supplies go missing. The project is then dead in the water, or has created a mess requiring much more serious cleaning efforts.

This is the first year they've gotten an overwhelming amount of stuff; and most of it wasn't from us. We did put a few toys up; mostly dolls that come with lots of accessory pieces. They're allowed to open new gifts when they dig out old ones to donate or throw away (if broken). We have a new baby on the way and just don't have room for the overflowing mess of toys (majority of which they don't regularly play with).

WE always did this with kids and skids, They get so much and it all gets lost in the mix, to pull out a barbie or 3 and some craft stuff and legos and put them in the closet, worked for us.
Then some rainy day when the "I'm bored" comes out, we have the gifts they forgot about from Christmas to play with.

Absolutely I do this! I can see my kid (1 yo DD) was easily overwhelmed with too many toys. As part of our re-arranging the house anyway, I put a chest of drawers in 'her' corner of the living room and put most of her toys into the lower drawers. She knows which drawers have what in them and can open the drawers. She hardly ever does, she's busy right now with walking around carrying her doll or trying to pet the cat.

In the future, that chest will be used to store activities. Can't tidy up if things don't have a place.

I think this is a reasonable idea. I tried doing it because DH thinks by showering him with gifts he will earn his love. The problem is we are headed toward financial difficulties and the kid's bday is coming up. Hello?? why so many gifts now and then get him a lot more for his bday? So I suggested we put a couple away and wait till his bday. DH looked at me like I was crazy! BUT yesterday I was trying to get a new phone ($80.00) because my phone is crapping th bed. Can you believe he gave me crap about spending money on myself for this? His kid ended up having zero for his dad, and all his dad could say was "Did you see that? Such a good boy. So appreciative". ok. Well, this skid (almost 16) refused to go to our wedding last month. So appreciative.
I dragged his butt out of the apt today to go get his dad gifts. Just opened his yesterday, but told me it was a little late to think about gifts for his dad. :? He grunted but got ready and came with me "I want your father to know you care about him even on days you are not over". We actually had a decent time. Who knew? Whether he goes back to ignoring him on days he's not here remains to be seen (I doubt much will change). The best predictor of future behavior is past behavior (Dr. Phil)

children get so spoiled and i know this was seen in my family in nieces and nephews. they would rip open the packages and then throw both the toy and the wrapping paper in a pile.

nothing wrong in keeping toys stored that were not remembered.
