The mother, Jumilah, took the attention in her stride, and perhaps her two-month-old cubs have been keeping her busy as at one point she produced a yawn which showed her huge mouth.
She gave birth to the two male and one female cubs on August 20, after mating with father Satu.
And the cubs will only be on show for short periods of time, as they tire very quickly for the moment, but as they age, they will spend more time on view in their enclosure.
Sumatran tigers can only be found on the Indonesian island of Sumatra - the only remaining stronghold for tigers in the country.
Experts estimate that there are just 400 such tigers left in the wild - and only 7 per cent of their original habitat remains, which is why these triplets are so important.

Louise Ginman, carnivore supervisor at Taronga Zoo, said she was purring with delight that all three tigers are healthy and strong, after Satu had been flowing in from Europe to breed with Jumilah.
'Satu was brought to Taronga from Germany as part of the international zoo breeding program for Sumatran tigers to mate with our Taronga-born female Jumilah and introduce new genetics to our region,'she told Manly Daily.
'The female cub is really cheeky, with a lot of attitude and is the first one to check out new things.
'The boys are more cautious, but theyre growing in confidence and body size each day, now tipping the scales over 6kg each.'
Ms Ginman continued: 'There are only about 400 Sumatran tigers left in the wild, so to see them here at Taronga and know that they are part of a safety-net in case wild populations go extinct is pretty remarkable.'
