So many people here suggest a book and a packet of seeds saying 'they go down a treat '. As if a 5yo is "thrilled" at receiving a seed bomb and a book from the works? 😂
We used to give stuff like a big bar of dairy milk. Or a bag of haribo. Or whatever hanging bags were on special offer. And would also chuck in something else. Things like whizzing balloons or gel pens or blind bags or whatever the latest craze was at the time and depending on age.
So what do your kids actually like in a party bag?
