In the car you asked to listen to your twinkle twinkle little star (not the regular version) it goes like this

I looked round at you in your car seat and you were crying, big fat tears running down you face. I asked you what was wrong and you said "Oh, the little girl in the song is sooooo sad because her mummy isn't there with her." and I asked where you thought her mummy was and you said "She has gone away"
Then you stretched you little arms out to me and sobbed "Please mummy, don't go away and leave me all alone" OK so now I got it and I blame Disney! All the princesses in your life (and you consider yourself one) have no mummys! No mummy for Snow White, not for Rapunzel, nor for Cinderella and neither does the Little Mermaid!
So, there it is! You have figured out I am going to leave you and you have been scared to let me out of your sight for weeks!
How do I sort it?
