Fountains, pools and lidos are great places to head with kids on hot days. London-baby.com has a brilliant list, including Kensington Memorial Park, with fountains, a sandpit and climbing frames; Diana, Princess of Wales Memorial Playground at Kensington Gardens, with water play area, musical instruments and sandpits, Duke of York Square in Chelsea, and the V&A museum courtyard paddling pool.
Fun creative activities led by artist Polly Brannan take place every Sunday for families at the galleries, where you can also see strange robotic sculptures by Bruce Lacey, and visit the cafe, bookshop and gardens.
