Are the favours for the adults or the children?
@Charlotte mostly adults to be honest
I'm not bothering with party favours mostly because we'll be spending a bomb on food for a huge BBQ. If it's something you're set in stone abpit doing them maybe a photo magnet of the person and baby? Freeprints do them pretty cheap and in sets of 3. Adults are usually happy with cake and socialising some you can entertain like kids and give them bubbles and fidget spinners and they'll be happy with that
Oh if it’s adults I wouldn’t bother - you’ll be providing the party so guessing there’s food and drink.
I wouldn't bother but make sure they are sent home with a nice bit of cake perhaps. I've received favours at christenings and stuff and whilst its thoughtful, it's unnecessary in my opinion
If you really have to maybe something small like - Bubbles Fidget spinners Magnetic stacking “rings”
