Do you regret having more than 1 child?

[Benq]

I'm turning 37 soon and have one planned child who is almost 6. Naturally the pressure is on from my mum and my aging eggs on when and if a 2nd is coming.
We've now settled into a nice routine. Most importantly, we still have time to do our own things. My husband and I both work long hours and one child makes balancing a professional life manageable. On weekends, it's easy to switch off when I go to the gym or my husband goes to do his own things. We like to travel to long distances and have a few trips planned with our son to Asia. Naturally, trips like those will be much harder if not impossible if we have 2.

I am very worried that I would be less happy with 2 young kids. But I see the appeal of having 2 adult children when I'm in my 50s-60s. Is it worth it to take away the free time that we have now for possible long term gain of having 2 children?
As a side note, I know lots of people have another child to give their first a companion. That is not a consideration of mine because I feel like it's not my job to give my child a companion nor it is a guarantee they will get along.
I should also confess that I am a bit selfish and struggled with a long PND. In addition, day care for a new baby + afterschool care costs will be huge. Would it still be possible to work full time? (part time is not an option in my industry).

I'm just trying to figure out if it's worth ruining my current situation for possible gain in the far off future? Thank you

Hi there, my personal opinion is that you have to do what’s best for you and not what’s best for anyone else including your mum. It’s your life not hers and the worst result would be it having a negative impact on your lives because you followed someone else’s hopes and dreams and felt resentful. I was always told that it was selfish to have just one but although mine get on, they lead their own lives now they are grown up and do their own thing. I’ve also witnessed the happy kids of my friends that are only ones and their fine and have lots of friends. I’ve given my two everything but I’ve sacrificed a lot and I worked crazy hours because I had to. I wouldn’t change having two because I’ve done it now but just think carefully about the pros and cons

I do I think. Well, I love my DC2 but I often hanker after the easier life I'd have if I'd stopped at one. DC2 has autism and it has damaged my relationship with DC1. But I was talking about that with DC1 recently and she said that if she'd no younger sibling she'd have spent her childhood wanting one! I could have bought a 2 bed place, could have got back to work quicker, could have had more freedom, life would have been easier. There's so much more to life than being a mother and caring and having all of that responsibility. I think I could have relished it if the responsibility had been 50:50 but I had to leave my x as he was so awful. I then couldn't afford childcare for two (complicated of course by DC2 having a SN, not even a serious one, he is in mainstream ed). But rationally, without sentiment, I do acknowledge that I could have had a better life and so could my DC1 if I'd stopped after 1.
