Hi It is dd2 4th birthday party on Saturday. Unfortunately she has broken her leg and will still be in plaster. She is getting very good at crawling and shuffling around but can not stand on the broken leg. We will have pass the parcel, but what over sitting down games are there?
Each person takes their turn at being the court jester. They have to make a funny face or noise. For every child they make giggle, they get a point. You could have a Gigglometer! The child with the biggest score/giggle rating wins.
pin the tail on the donkey? - she could shuffle up to the picture.
chocolate game - if you throw a 6 you put on hat scarf and gloves and then try to eat bar of chocolate with a knife amd fork - said bar can be wrapped in newspaper/wrapping paper first too. die continues to be passed round the circle and you continue to attack the choc until the next 6 is thrown
some kind of craft activity - ice a bun/biscuit, make party hats...
I know it's too late for you but, mystifyingly, the most popular sitting down game I've done is bingo. Themed usually. So Narnia bingo, Halloween bingo etc. I make the cards in word with clip art. They're a proper faff but the children all love it and it makes a good ending to the party.
