To keep trying to persuade my partner to have a third child

[Goldalocks]

We have two beautiful children aged 4 and 1, a boy and a girl (so various people have mentioned the 'perfect family' which I find a bit silly as 2 boys/2 girls would have been equally good!) However, I cannot stop thinking/planning about having a third child even though my partner is fairly adamant he does not want this. He thinks practically in terms of the lack of sleep with another child and being able to afford much more for the 2 we have. I have always imagined myself having three children - I always thought this would be a nice number, a little gang while not being ridiculously many - and feel so sad at the thought of never being pregnant/ giving birth and having the excitement of a new baby again. Also, I worry about the future and what (god forbid) if anything happened to either of our children - having three just seems safer somehow although I do not even like to tempt fate by thinking this thought.

I know I am very lucky, but I can't stop thinking about this and it is making me unhappy when I should be content with what I have. Anyone been in a similar position of intolerable broodiness/ have any advice?

I know this is like 6 years later but what happened? Third child? My husband and I have 2 kids, ages 5 and 3. I am desperate for another one and he said we don't have enough money. There is no compromise and I'm super said especially during the time in my cycle where I know I'm most fertile. I feel like I would do anything to try just one single time. So I'd like to know which of you did get your third??
