How long have you been with your present partner? That’s the first thing to think about when considering bringing a human life into the world.
I wouldn’t suggest anyone tries for a baby until they have been with their partner for a good long time, like a few years, and are in a stable relationship. That they know each other really well and are likely to stay the course together, knowing each other’s flaws etc.
So if that doesn’t apply here and you’ve only been together since lockdown last year it if you’ve been dating a couple of years but barely see each other due to lockdowns (and don’t know each other that well) I’d suggest you don’t try for a baby.
Because you are 42 it could be that this could be your hormones talking, as you are at an age which you know it’s now or never. It may even be too late already. Your hormones could be making you feel like this. Mine did that to me. I ignored them as I knew a baby wasn’t right for me at my age.
The chances of having a disabled baby rise with parents age too. Could you cope with a baby needing extra care into childhood and perhaps adulthood?
Bad things may have happened in the past which made you unable to care properly for your children but you can’t change that.
There’s a lot more to consider than whether the ss would be involved or not.
