We have decided to stop at one and are asked so often when the next one is coming - DD is nearly 3.
At the moment DH works about 70 hours a week and I'm just not prepared to do it alone - when DD was born DH worked much more family friendly hours so was able to be really hands on.
DD is a happy, outgoing, sharing, loving and confident child and I have absolutely no concerns that she will be spoilt or lonely. In actual fact I think I will make more of a conscious effort to encourage her to mix with other people & children. She has also developed a lovely friendship with another girl who will also be an only child.
Sometimes I do wonder if she will 'miss out' on having a sibling, but tbh how many people these days have a close relationship with their siblings.
Some people have said 'Oh, but you're so good at it' meaning being a mother - but I know that the only reason for that is that I'm able to put everything into it because there is only one - if I had any more I know I would be too tired, grumpy and constantly shouting at the children as I really am a nightmare when I'm tired.
We are thinking about adoption or fostering in the future, but that wouldn't be until DD was much older.
I do sometimes feel sad that I won't feel a baby moving inside me or have the feeling of holding my newborn baby in my arms, but those thoughts are few and far between and I really do love it just being the three of us!
