The first successfully delivered baby gorilla by caesarean section, is now six weeks old and developing well.

Bristol Zoo keepers says she's almost doubled her birth weight, now weighing 2.2kgs, has started teething and has even giggled for the first time.

She's still to young to be shown to the public and is being handreared round the clock by a small team of experienced gorilla keepers.

The baby girl now needs a name, and people are being asked to choose their favourite name out of these three choices.

1. Maiombe (a geographical region in Africa covering gorillas’ native countries)

2. Afia (meaning ‘Friday born child’ in Ghanian)

3. Pianga (Pianga from PiangaMakeshi, a place in the Democratic Republic of Congo).
