Answer:
they aren't ready to have a child although John is kinda ready (like in a neutral way) like baby comes fine if not fine kinda situation . soon in like 2,3,4 years I guess it will start giving him concerns, his wife may not be and needs more love and guidance in her life, and also the couple needs to gather money and talk about their financial plans and stuff like that if a baby comes into the picture.
I would say since John doesn't have a problem having a kind 59% comes from him, then his wife (According to the passage "Laurel wants to have kids 50% but) the "but" removes percentage possibilities of her having a child making it reduce to 25% .
so 50% + 25% = 75% ready to have a child
also by evaluation they are possibly gonna have one to two children.
Hope this helps
Ace that work
Good luck ✅
