When my son and his then girlfriend became more serious, his girlfriend asked me out for a meal so that she and I could get to know each other better, which I thought was a lovely idea.
Anyway, part way through our lunch she brought up the subject of her having children - I would have never asked her about it - and said that she was very sorry, but that she didn't like babies or toddlers at all, so she wouldn't be having children.
I love being a mum, but I said to her very honestly that I was pleased that she and my son weren't going to have children if they didn't want them, because I felt then, and I still do now, that only people who actively really want children should be the ones to have them. I feel very sad for those that do want children but either can't have them, or are struggling very hard to do so.
I believe that far too many people have children because of an accidental pregnancy, or without giving it real consideration. So I was very happy that she knew her own mind about it (and of course I hoped that my son felt the same way, but I didn't say that to her).
I hope I don't sound arrogant or anythin̈g, and/or that I think that I am a great MiL, as I really don't believe that I am anything special at all. I made lots of mistakes when my boys were growing up (I did try to learn from the mistakes so that I could hopefully do better next time), and unfortunately I have unintentionally said the wrong thing to each of my DiLaws on occasions, but as soon as I have realised that I have done so, I apologise.
I have also asked all my children - both birth and in-laws - to please let me know if I ever say the wrong thing, especially if I have upset any of them in the process. I suppose I am a great believer in communication as I think more of us need to try quite a bit harder in that respect.
