jayjay - my 5 year old asked me how the baby got in my tummy. I told her that Mummy and Daddy decided that we love each other and them so much that we wanted another baby. Told her that we had a 'special cuddle'. I also explained to her that i have some eggs in my body, and daddy has something special that helps the egg to grow into a baby. She was happy with the explanation, and didn't ask anymore questions (thank goodness!!!)
