How did timing for kids work for you? My husband is close to finishing his 1st semester of his 1st year and is wanting to wait a WHILE for kids! He wants to wait until the end of his 3rd year to even try to have a baby. I don't want to wait. I'm older than him by 2 years and it's hurting me (crying literally daily) to wait. How did your spouse and you decide the timing for kids? I'm struggling and it's honestly turning me off from my husband. Like, this is a HUGE deal. I feel like if I don't talk about a baby, I'm hiding my feelings/thoughts, but if I do talk about it, I get lectures for 30 mins (or longer).
