Hi everybody.. Hope you're all well in lockdown. My little boys 2nd birthday is coming up August. At the moment he's really into working things out like concentrating on clipping the dogs collar together or clipping his pram bar into the holes. I was wondering if anybody knows any mind challenging toys/games I can buy him suitable for his age? He kid of needs the challenge as stuff like mega blocks etc once he's done it he's not interested again he really like a challenge. Thank you everybody xxx
