I had my bedroom completely redecorated for my 18th, and a ring with my birthstone from my Dad which I still wear on a chain now my fingers are considerably fatter!
My DD is turning 18 next month and I'm taking her to London for a long weekend. We've got some lovely restaurants booked, Sky Garden, Hamilton Tickets, a cheese tour and indoor crazy golf which her aunt, uncle and cousins are joining us for.
I'm doing a lucky dip of 18 small gifts for the actual day...scratchcard, vodka and peach schnapps miniatures, chocolate, novelty pasta, nail polish, book of quotes, concertina file with all her adult documents in, scented candle, mug, personalised keyring with a scannable link to a Spotify playlist of songs from her growing up that have special memories attached, a couple of £10 vouchers/gift cards for shops she likes, 18th birthday badge, personalised shot glass...
There is a ring she'd like as well but that will be a last minute add on, finance permitting, if her dad doesn't get it for her.
