My daughter has never been the kind of girl to sit down and play with toys in a little world of her own.  I loved doing that when I was little.  I always managed to play games and think  up an imaginary world.  However my little one is not quite the same.  Maybe 3 is too young I dont know.  She is more about making a mess.  So I needed 20 minutes one day to get something done and she would not let me so I made up a bit of a messy game for her .

She got a bowl , flour , lentils, eggs and water. She loved it . She played with this for ages and said she was making a Happy birthday cake for dada . I put in a little food colouring for her and made it turn blue

Not expensive and can add lots too it.  Next time I am going to get some glitter too
