Chomping on cake and fresh from a trip to a play farm, little baby Euan enjoyed his first birthday just like a normal child.

But with Euan last year making medical history by becoming the world's first baby born naturally to a mother with an artifical pancreas, the day was extra special for his parents Catriona Finlayson and Peter Wilkins.

Mrs Finlayson, who is diabetic and took part in a treatment trial run at the Norfolk and Norwich University Hospital, said: 'It felt quite emotional and we had such a lovely day.

'Euan is a very happy baby who smiles a lot, and is a very good eater.'

Since the birth - hailed by doctors as a breakthrough in the treatment of diabetic mothers-to-be - the family have moved to Bath, from where Mrs Finlayson runs her face and body painting business while looking after Euan and his older brother Finley, 7.

The family were joined for Euan's birthday by his grandmothers Sue Wilkins, of Knapton, Rosie Smith, and step-grandfather Ian Smith.

They took Euan to a farm where he could play and watch animals, before celebrating with cake at home.

His godmothers Jennie Roberts and Grace Williams, both of Norfolk, took part in the celebration via internet video telephone system Skype.

David Booth, the N&N's chief of women and children's services, said: 'We're really pleased that both Cat and Euan are doing so well.

'Treating diabetes in pregnancy can be particularly challenging because hormone levels are constantly changing and blood sugars can be difficult to predict.

The study, which Mrs Finlayson-Wilkins was a part of, is ongoing and its results are expected to be published later this year. If the findings are positive, this may pave the way for this technology to become available for more women with diabetes who conceive in the future.
