Bertie and Boo Adventure Island on Balham High Road is a soft play centre that clearly has its act together — parents throwing birthday parties here repeatedly mention how smoothly the staff run things, leaving grown-ups free to actually enjoy the occasion. The soft play itself is well set up for little ones, and the venue is buggy-accessible with a likely kids' menu and highchairs on hand; just note there's no baby changing on site. It's an indoor-only space, but for a rainy-day adventure or a stress-free family celebration, it's well worth considering.

The secret to a calmer meal out? Something to do that isn't a phone. Each pack is full of screen-free bits and bobs to keep little hands busy at the table and buy you a proper sit-down. Three printable packs, one for each age (toddler, preschool, primary) — free, straight to your inbox.
