:00:00. > :00:08.Morning everyone, I'm Leah and you're live with Newsround.
:00:09. > :00:12.We've got the latest from the ski slops in Norway.
:00:13. > :00:25.A bronze age wheel is found in Britain
:00:26. > :00:29.First to the story of three sisters Casey, Hannah and Lucy.
:00:30. > :00:31.Hannah, the middle sister, has a condition called selective
:00:32. > :00:33.mutism, which means she doesn't talk in public.
:00:34. > :00:35.Here's the story of their family, which they've filmed
:00:36. > :00:47.Hannah, what is the best thing about being a sister?
:00:48. > :00:57.And what is the worst thing about being the middle sister?
:00:58. > :00:59.If you cannot already tell, Hannah has selective mutism,
:01:00. > :01:02.so it basically means she doesn't talk in public.
:01:03. > :01:04.She only talks to me, my mum, my dad and Lucy.
:01:05. > :01:08.She doesn't talk to anyone else outside of school,
:01:09. > :01:16.but she only talks in the house if no one is there.
:01:17. > :01:19.Hannah's condition means the person with it gets worried and anxious
:01:20. > :01:25.when speaking in certain places like the public or in school.
:01:26. > :01:28.It doesn't mean they don't want to talk but feel they cannot,
:01:29. > :01:31.The condition affects one in every 150 children.
:01:32. > :01:33.It means that Hannah relies on her sisters to communicate
:01:34. > :01:36.with her and to speak for her, and to explain why she is not
:01:37. > :02:14.Yes, are you going to write that down, then?
:02:15. > :02:17.I am really happy that Hannah trusts me and Lucy to speak to us,
:02:18. > :02:21.it shows the bond between the sisters.
:02:22. > :02:24.Casey and Lucy say they hope she will be able to talk
:02:25. > :02:29.in the future but they are happy to wait until she is able to.
:02:30. > :02:31.And you can head online to watch Brothers and Sisters,
:02:32. > :02:39.That's where you'll also find more on what it's like growing
:02:40. > :02:42.up with step brothers and sisters and hear what children
:02:43. > :02:45.Next, to the Winter Youth Olympics in Norway.
:02:46. > :02:47.Later today, all eyes will be on 17-year-old Cal Sandieson
:02:48. > :02:49.when he takes part in the Ski Slopestyle final.
:02:50. > :02:56.It is 9am and we are already on the slopes.
:02:57. > :03:00.You have got lots of training to do so you'd best be off and I will meet
:03:01. > :03:03.you at the bottom with a hot chocolate.
:03:04. > :03:06.Cal is 17 years old, his sport is Slopestyle,
:03:07. > :03:08.which means he has to perform five tricks down this
:03:09. > :03:46.How do you feel for tomorrow, are you prepared?
:03:47. > :03:51.Was there anything trickier that you did not expect or anything
:03:52. > :03:55.It was a little bit windy and stuff but it was nothing out
:03:56. > :03:58.From zero to ten, ten being the most confident,
:03:59. > :04:07.What happens now for the rest of the day?
:04:08. > :04:11.I will normally go down and chill, make some food, get to bed early
:04:12. > :04:17.Nice, that sounds good, shall we head off and eat?
:04:18. > :04:21.Make sure you join us again at 8.15 when we'll be speaking to Hayley
:04:22. > :04:23.live in Norway for more on the Winter Youth Olympics.
:04:24. > :04:25.And head online to see more of Cal showing
:04:26. > :04:33.A Bronze Age wheel, believed to be the largest and earliest ever found
:04:34. > :04:35.in the UK, has been discovered in Cambridgeshire
:04:36. > :04:41.Archaeologists say the rare find is incredibly exciting and shows
:04:42. > :04:45.This is what the area might have looked like back then.
:04:46. > :04:48.They hope this find will help them to understand more about the Bronze
