You both have to be in agreement for another baby to work. That being said, if you are planning to stay at home while your kids are young, and go back to work full time when they start school, you could bring this up. The further your kids are in age, the longer you are going to have a little one at home, so therefore, the longer it will take you to go back to work. I don't know if finances are a big deal or not for you, but you never know what will happen, and if you are a big believer in trying not to use daycare, this may be something to think about. If you have to work to make bills, and your baby is just going to end up in daycare pretty quickly, he is probably thinking about that, and that is contributing to his decision to wait for another child. I'm sure there is another reason for him to want to delay having another child other than just being happy with one. You just need to have a candid, non-confrontational discussion with him about it. He may not agree with you even after the discussion, but hopefully you will understand each other's reasoning, and be respectful to each other until you are both ready.
