London, April 23 (TIWN) UK's Prince William and his wife Kate Middleton have marked their youngest child's Prince Louis second birthday with new photos of him doing some rainbow coloured hand-painting for the country's National Health Service (NHS), it was reported on Thursday.

In the shots, captured by his mum Kate at their home in Norfolk earlier this month, the toddler can be seen beaming as he playfully holds his hands up to the camera. His brown hair is neatly combed and he is dressed in a smart blue gingham-style shirt.  Rainbows have become a symbol for the NHS during the coronavirus crisis, with children across the UK putting drawings and paintings in their windows as a sign of support.  Another photo reveals Louis’ finished masterpiece, framed with a green border. The Prince, who is the youngest of Kate and William’s three children, turns two today and will celebrate with his family at home.
