The only thing I can think of is a wishlist for close family if they've asked for it
. When I was a kid I had to make a list for my mom of what I wanted for xmas, birthdays, etc (not
that I got everything on the list, or
that I only
got items on the list - she always phrased it as "ideas for gifts" so that's been drilled into my head for as long as I can remember!). If someone wasn't sure what to get me, they called mum up and she told them what I was really "into" right then. You know, she loves ponies but doesn't play with her princess dolls or something along those lines.
I just can't see taking a 4 year old to register for their birthday...
Or, well, anyone really. My family does amazon wishlists but that's because we have this bad habit of asking the person what they want over and over again because we forget. In practice it's a list of ideas and mostly it's used as "she's up to X book in this series, so now I know not to get the earlier ones, and oh, she's got Y video game listed so it looks like she doesn't have it yet". We don't even buy off the lists online - it's just for reference.
