We would never ever have another child because we felt the one we have needs a sibling. It would be because we want another child to enrich our lifes and be parents to.
Our goal as parents in our eyes is to raise a respectful, functioning, able-bodied (chores wise and house hold wise) kind, caring, considerate son who's life is filled with love, affection, acitivies and adventures. We love being parents and can honestly say our life has been 100% times better since he came along. He is our pride and joy. I had a great pregnancy, great bf'ing experience, great maternity despite being lockdown and didn't suffer PND, PP so I think it makes me question why I don't have the desire to have another child when we really do love it. We have loved all the stages and spend most nights playing video and photo roulette where we pine over the baby baby days. If we could push reset and do it all again with our son we would in a heartbeat.
I am an only and don't feel burdened with my parents getting old. I actually think it's nice to make all the decisions for them, and not have to consultant with anyone, at least there is no fighting or someone to have disagreements with. I also don't think I am selfish, or weird, or lonely or annoying haha. But of course people will argue that of course I wouldn't. I have lots of close friends, an amazing relationship with my mum and give relationships with people my everything maybe because I don't have siblings so I don't take them for granted.
If we decide to stick with an only, we will invite his friends on holidays, always make them welcome in our house and allow our son to have as many people come and go as he likes.
Financially the world is getting more challenging, we don't own a house and live in London which we love. I know our lifestyle of going out for dinner with him and on bike rides and all the fun later night park dates and meeting daddy after work for dinner or to go to the shops for a wander just wouldn't be so easy. We would like to be able to save for his future currently saving £100 a month for him when he is older which we just couldnt do with 2. All practical things to think about too such as driving lessons, cars, house deposits, uni, weddings not just about materistic things or holidays.
Thanks again for all your input, it really is interesting to read and made me think about things from all different angles and given me lots of food for thought.
