So I have a good friend who has a DS born a few months before mine. I got the invite for his 1st b-day party this month. I always like to ask parents beforehand when I go to a kid's party if there is anything they don't want their child to have. For example, my SIL doesn't want her kids having stuffed animals. So I know to avoid those. Some people don't like busy, loud, light up toys. I do this because 1. I don't want to upset anyone and 2. Because I don't want to spend money on something that will get tossed or ignored. My friend e-mailed back and thanked me for checking with her, and then mentioned that she set up a registry at BRU with "some ideas." Is this a thing??? I very much like her, so I'm not trying to be judgmental. But I understood registries to be for bridal and baby showers. Before there was a baby. I can see her ideology. People like me who ask what should/should not be purchased would be able to readily access what she would prefer her son to have. But I also feel like it should be handled in the sort of exchange we had. Casual. "Hey, anything you don't want?" "Just no more clothes or battery operated toys! Thanks!" Maybe it's me. Hence, the post.
Edited for typos.

Re: First birthday registry?
First birthdays around here are for the grandparents and aunts/uncles. We hang streamers, I bake a cake, and we call it a day. I really don't get the big deal and why a registry would be necessary?
For other folks who ask, we'll probably give more general guidelines. Clothing for this season in that size, if they get a toy it shouldn't require batteries and they should only get her one toy, etc.

I do add specific toys or books that are age appropriate that I personally want to buy them. Amazon also lets you free text items into the wish list - so I will add "fall/winter clothes, size 2T" or generic things like "puzzles" or "art supplies", without picking out the exact brand, design, etc. I have even added diapers and wipes on there in the past.
We live no where near our family. Often times when they want to buy something for the kids, they don't know if we already have it. So this help them out. They also enjoy knowing what size clothes to buy.
Our sister in law does this for her kids too, and it doesn't phase me at all!
I think it's actually quite helpful for people who want to buy a gift but have no idea - we recently went to our neighbors for dinner and they pulled out some toys for DD that were the PERFECT developmental age at 7 months... We bought them for her 1 year-old. A wish list would have been helpful.

I have an amazon wishlist for both DDs (and myself), and I send the link to my ILs and anyone who asks at xmas and bday time. I make sure that there are a range of prices represented (from under $5 up to about $40) and sometimes just pick a toy that is representative and make a note of that (for example we wanted a soccer ball for DD1 so I just found one on amazon, put it on the wishlist, and made the comment that any soccer ball would be fine, this was just an example).
I love it when my godchildren or niece has a wishlist because I otherwise have no idea what they like, what they already have, what the parents don't want, etc.
I also agree that since she just sent it to you because you asked about a gift, it was fine.
