My partner say he wants children but....

I’ve always wanted children I’ve definitely taken care of them before for very long periods of time when their parents were messing up,1!: nothing has made me feel happier and more balanced and at peace children never stress me out even when they are difficult my childhood was very hard and I think that’s part of the reason I’m so driven to want to make an impact on children as a woman, my partner had a very fantastic childhood, amazing parents, and has never taken care of or even held a child in fact he struggles to communicate with kids it’s honestly kind of sweet he’s just so awkward and a little scared .... He always feels like we aren’t ready he’s already in his 30’s and I feel like he may never feel ready and let the opportunity pass us by on top of that My family had a disposition to early menopause and I honestly would feel shattered if I never had the opportunity to have my own child, how do I make a good argument for having children? I feel to an extent we may never feel completely ready it’s something you learn as you go.
