I find myself constantly worried about going through all that again. We're at the stage where thoughts of number 2 arise. We're not 'trying' (I really hate that expression) but at some point, we will have to consider the timing of it all. I've written on here before that I think you'd always feel guilty about stopping at one child, yet you'd never feel the necessity to add a third to a brood of two; I said to a friend of mine recently that you could always have an 'accident' pregnancy 5 or 6 years after the second and he said that would be just as bad as having an only child. I've never thought of it like that, but there's 11 years between him and his brother and as far as he's concerned he felt like an only child. Maybe he isn't lumbered by some of the behavioural traits that some only children develop, mainly because he's not an only child, but he felt he missed out somehow. There was always this elder brother, but he couldn't relate to him, couldn't bond like he did with his parents. There was always too much of a gap to bridge and at every new stage of each of their lives, the other was at a different one. So, while they're not strangers, they're certainly not mates and it's no one's fault, just bad timing.
And that's the point isn't it; it's about how it affects the child, not our selfish 2.4 children, 4x4, black Labrador, suburban ideal. So, the gap needs to be enough but not too much. I also think that there's a sense of the sooner it starts, the sooner it'll be over. I.E the hell of sleep deprivation. I'm sure it's not just me but I really do think that's head and shoulders the single worst thing about parenthood. I certainly feel that I've got it in me to do it once more but then, unless I have the money for a live in night nanny, I'm done. So, I totally get why people stop at two but also wouldn't judge anyone who stopped at one. I do think you'd regret it in the long term when the memory of sleep deprivation fades.
Hopefully as his appetite gets fully back on track he'll add the extra hour and half to his sleep pattern which is currently missing and that makes all the difference to mum and dad's sanity!
