Any advise or should I just not say anything?

Me (24 F) and my husband (31M) just got married. I've told him before we got married that I wasn't really interested in have kids and if we did that it would be a one and done kind of thing. Right before the wedding I told him I didn't want one and after the wedding I still feel the same way but I know it kills him becuase he loves kids and would be an amazing father. So here is my question I've been thinking and thought if I do give him a child I don't want to handle the hard parts like waking up in the middle of the night waking up early of course I'd help with diapers and stuff like that but do you think it's a good idea to bring up or just leave it as no kids

Any advise or should I just not say anything?
