Take the littlest family members to soak up the sights and sounds of Chinatown. Impress their little fingers with dolphin-shaped dumplings and touch screen ordering at Chinese eatery China Red.
Start out on Southbank where the kids can run around while you stroll with your hard-earned coffee. Take them down to marvel at the aquatic wonders at the aquarium, keep with the marine them and make like pirates at Polly Woodside, or give them a bird's-eye view of the city from Eureka SkyDeck.
Pack a picnic and explore the Botanic Gardens. In summer, catch a show in the gardens – outdoor theatre, staged for kids big and small. If outdoors isn't an option, check out the kids' events program at the Arts Centre, National Gallery of Victoria and State Library of Victoria or book in for a matinee session of one of the big shows in town.
For interactive play, see what's on at ArtPlay at Birrarung Marr, a great kids' space running workshops and activities in music, art, theatre – any kind of play – for babies and children.
If the little ones (and you) are still going, consider a visit to Melbourne Central where the family can choose from a range of eateries and flop in front of a movie.
Throw all the animals in together and take the family to one of Melbourne's zoos. Let the kids run free at the Growing Wild exhibit at Melbourne Zoo or head out to Werribee Open Range Zoo for a safari adventure.
