Recently it was my DN's birthday and my DC's birthday. (DN is a young adult, DC is primary age).
My Dsib and I usually don't post presents after a few have got lost in post and give them when we see each other, which isn't very often due to distance.
Recently we saw each other for first time since the birthdays and I gave DN a nice and thoughtful present worth around £50 and a personalized card.
My primary age DC got nothing, not even a card. Luckily as it wasn't their actual birthday they didn't realise. I think my dsis has forgotten about it but not even DN getting their present prompted a remark.
This isn't the first time she's been a bit crap over gifts, when it was my other DC's birthday she gave him a cheap and novelty second hand book that wasn't even appropriate, wrapped in Christmas paper (we saw them at Christmas) that I assumed she'd grabbed off her DC's shelf. We have my BIL a generous voucher for his big birthday and my DH got nothing from them.
At other times she can be very generous with hand me downs and hosting etc.
It's worth adding they have significantly more wealth than us.
I just feel a bit shit about my DC getting nothing.
WWYD? Not sure whether I just chalk it up to how she is and carry on, reign in gifts, or be frank with her and pull her up on it. We get on well but don't have the sort of warts and all relationship where it's easy to point out her faults and vice versa.
