Malaysian Borneo and Brunei are great for family travel, especially if the kids like monkeys, flowers, bugs and vibrantly variegated temples, food and fauna. Babies will attract a lot of adoring attention.
Destinations with facilities and activities for children include Kota Kinabalu, Sepilok and the Kinabatangan River in Sabah, and Kuching, the Santubong Peninsula, Bako National Park, Semenggoh Wildlife Centre and Gunung Mulu National Park in Sarawak.
In Malaysia children receive discounts for both attractions and public transport.
Cots are not widely available in cheaper accommodation. Some top-end places allow two children under 12 to stay with their parents at no extra charge.
In Kalimantan only Balikpapan has hotels that specially cater to children.
Baby food, formula and nappies (diapers) are widely available, but stock up on such items before heading to remote destinations or islands.
Lonely Planet’s Travel with Children is packed with useful information.
