We used to spend approx £50 each on parents (4 of them), £30 each on siblings and their partners (4 of them) and £30 each on our two neices. So around £400. But since DS came along we've cut right back. We now spend £50 between each set of parents, £20 between siblings and their partners, and £15 each on our neices. So around £170. We don't buy for grandparents, aunties/uncles or friends. And the gifts we do buy are from the three of us, we don't spend extra on gifts from LO. We used to give our neices money in a card for xmas and birthdays once they hit teenage years, but now they're 18/19 and have their own jobs so I've started just getting small gifts. This year they've got necklaces from the Hot Diamonds outlet shop so I only spent £14 each but their gifts are worth £50. Pleased with that!
I do spend around £30 on a gift for my best friend's daughter who is the same age as DS. She does the same for LO though and we always swap gift ideas so she buys something I had on my list for him and vice versa, so it doesn't really cost anything I wouldn't have been spending anyway IYSWIM.
For DH I just get token gifts from LO, we don't really get each other gifts because we'd rather put the money towards a holiday or something.
