I have a two year old who is so clingy at the moment. If I even go to the toilet, she starts crying and saying "Mummy gone away". She has to be with me all the time. Is this just a phase and should I just keep reassuring her that I am still there? I have tried to ignore it but it is not working. She has had any major upsets recently so I am not sure what has caused it. Any suggestions would be appreciated.
