My in laws are lovely decent people and kindhearted. However I have a major issue with present buying for my kids. Every Christmas and birthday we're inundated with messages from SIL BIL and PIL "what do the girls want for Christmas/birthday", these always come after I've done all of our own shopping for them, I then have to think of (very specific) presents that they can get them and I have to tell each person a different thing so they don't overlap, I have to give options so I'm not being greedy and suggesting something that's outside their budget (they never tell me the budget though).
I've tried saying for example picture books (for 5yo) or something with crafts (for 10yo) but I'll be met with "what exactly though?", "what colour would she want", "where can I get that?" "is that in Argos, what page is it on" etc etc etc. I often end up going into the shop and physically buying a present from the PIL and they hand me over twenty quid. The reason it all bothers me so much is that they buy for my nephews without any prompting gifts that they love, not just at Christmas or birthdays either. They take an interest in the boys so they know what they're into but they're stumped when it comes to my kids even though if they just talked to them for 10 minutes they'd find out they've got loads of hobbies and interests and they're really easy to buy for.
I'm getting really sick of it, my DD birthday is coming up in April and again the questions will start, separately from 3 different couples who couldn't be bothered to go into a shop or look online and choose something they think a little girl would like for her birthday. What can I do? How can I tactfully tell them to go off and figure it out themselves?
