DD: Leagaly you actually don't have to tell your boss at all! the only thing you have to do is hand in a letter to say you will be taking maternity leave - the maternity leave law has changed - before it was 12 months then you had to come back full time. Now it is one year - with and option of going part time at the end.

I hope you boss is good to you.

Luckily for me i had a boss who was over the moon about me being pregnant - so it wasn't hard to tell him at all

Good Luck with it
