My son is 5 and currently an only child.
He was 18 months - 3 during the lockdown/Covid time. And it didn’t feel like a good idea to have another baby at that point, although this would have been the time we’d choose, if it wasn’t for Covid.
I know some will say it’s not too late, but I don’t feel like I could go back to sleepless nights, night feeding, nappy changing and so on.
But conversely I feel sad he won’t have a sibling either.
