Called my Mum to tell her about the pregnancy. She is stuck in Gran Canaria because of the Icelandic ash cloud but she was excited about the news. It wasn't more than an hour or so later that I had a call from my brother-in-law to wish me congratulations - trust my mum to spread the word :)
I did get to tell my other sister myself and I haven't been in touch with the last sister yet.
In the afternoon my father-in-law came round for lunch. He has had a lot of bad news recently, with his mother dying only a few weeks ago (Rachelle's other nan - she lost them both within about a month of each other) and a number of other things. To say he was happy is probably an understatement.
Just have Rachelle's brothers and sister to go now... The rest of the world can wait another few weeks.
