Can anyone help?
This is how I've tried to explain: for a baby to be made a man and a woman have to be together in a special way and mummy and Tom were together and then ds grew in mummy's tummy. Tom went away but mummy was happy and loved ds very much. Then daddy came and loved mummy and ds and looked after us. I also referred to Tom as his "birth daddy".
I drew some pictures of men and women and babies to illustrate but I don't think I managed to get any message across!
How can I make it clear for him? Are there any books explaining this sort of situation? Maybe he's just too young to understand?
