My dd is 13 months and she was fine all day yesterday until we gave her, her dinner she would only eat a few spoonfuls (not like her) and then she just refused. So we got her out of her highchair and she screamed if we put her down to play with her toys and she just wanted cuddles which was unlike her as she prefers to be playing on the floor. We then gave her a bottle and after we put her in her cot she threw up everywhere. After we got her changed she cried if she was put down. In the end she went to sleep but she woke up at about 5 crying and she had a fever so I gave her calpol and she did seem ok but she's still refusing to eat and if we put her down she cries until we pick her back up
What could this be?
