Players Nathan Hughes and Hugo Southwell from London Wasps Rugby Club visited children at the hospital in Ascot last Thursday , along with club mascot Sting.
They spent time chatting to the youngsters, handing out goodie bags, signing autographs and having photographs taken.
Mr Hughes said: “We came down to help spread a bit of Christmas cheer, see the children and help brighten their day.”
Mr Southwell added: “It’s great to come and see the kids at a time like Christmas and we wish them all the best for their recovery.”
The following day, on Friday , employees from outdoor company Timberland Uk hosted its ninth annual Christmas party at the hospital.
Children from ward 24 were treated to a festive disco, party games and a visit from Santa where he gave each of them a present.
Sarah Fowler, a member of the company’s customer service team, said: “This is our ninth year of coming to the children’s ward at Christmas and we absolutely love it.
“We supply the food and entertainment, and wrap the presents which are supplied through our partnership with Hasbro. Without them we wouldn’t be able to do so much.
“The children and their carers just need to turn up and have a good time. It really is great fun and something we look forward to every year.”
Ros Rushworth, lead nurse for paediatrics at the hospital, added: “We cannot thank Timberland enough for all the support they continue to give us.
“To host the children’s ward party for the ninth year running is incredible. It always lifts the children’s spirits and it was lovely to see them enjoying the festivities with their families and the staff.”
