Hey OP, you’ve had some great suggestions here which I hope will help.
I just wanted to say I share your pain. I have 15 yr old twins and we struggle trying to explain the visual presentation. DS wants small expensive gifts (eg PlayStation games) while DD likes cheaper gifts that tend to be larger, such as new art sketching books etc.
DS cannot understand that their two piles might not look different. He also cannot wrap his head around them having a different number of gifts as that wouldn’t be fair. No matter how many times I try and explain the concept of monetary value, he can’t grasp it.
So solidarity 😂❤️
I adopt many of the measures above and it works well. I wrap everything 😂 A multipack of socks - for example - split apart into each individual pair wrapped separately and then tied up in a big bundle together. That sort of thing adds bulk.
Get some small gifts that are themed similarly. Wrap them all individually and then put them all in a large cardboard box filled with bubble wrap, packing peanuts, shredded paper etc. Then tape up and wrap the box. I do stationary like this sometimes - lots of miniature stationary gifts all wrapped and in one box. DD loves stationery.
I also create things that slow them down. So for example, I bought DD a new zipped pouch/bag thingy for her birthday and then I filled it with lots of different hair clips. 61 hair clips to be precise 😂 (DD had asked for hair clips). So investigating the contents can be quite intriguing and when that’s combined with bulky wrapping techniques, it can help to create the impression that there’s a lot to open.
(Also, as an autistic woman myself, the idea of being able to get the contents of a box/bag and organise them all is somewhat exciting! 😂)
I hope this thread has helped 💐
