Hi, Mumbai has a lot of family-friendly places to visit, depending on the kind of experience you're looking for. I'd recommend visiting Siddhi Vinayak Temple or Haji Ali Dargah for a spiritual experience, Colaba Causeway or Linking Road for street shopping and Gateway of India, Bandstand or Marine Drive for some quality time by the sea. You can also plan a visit to nearby destinations from Mumbai like the popular amusement parks such as Essel world and Imagica or even plan a getaway to Lonavla or Alibaug if you prefer being close to nature.

Temples: Siddhivinayak, Mumbadevi, Mahalaxmi and Babulnath
Gateway of India, Nariman point, Girgaum Chowpatty, hanging garden, Haji Ali
All of the above can be done in a days time, though to avoid the crowd and traffic start early in the morning.
Borivali national park is also a good option for a family outing.
