I spoke to my mum this afternoon. She asked how much longer it's gonna take for us to make her a grandmother again (we've only been trying since October) and that she'll be old and grey by the time we get around to it. I told her she already was old and grey....pmsl, she didn't take that well, lol.
I was sooooo tempted to tell her, but I really want to see her face when we do.
The OH asked me after talking to her, how I was planning on telling her and my sister. Whether we should get them a little gift as a clue, such as a bootie each. But we've decided to ask my sister (in front of my mum and BiL) if we can bring someone else to stay with them next Christmas. When she asks who, we'll say we don't know as we haven't met them yet and won't until they arrive in August...see how long the penny takes to drop....lol.
