Husband dropped the hint.....men get baby fever too?

So my husband is 49 years old, I am 31. We met at work and fell in love. Blah. Blah. Blah that isn't my story. Our son, who is 11 months old (the cutest baby ever) is his first and only child. My husband was the last chance to carry his family name (awww 🥰) and we got our boy! My pregnancy wasn't the worst around but it definitely wasn't as easy as my two older children. But we really always said this was our only baby. But now that our baby is growing up, my husband made the comment about 2 months ago (this was out of the blue) "do you think it is fair that we put all this pressure on Dawson to carry my name?" I had to take a second to hear what he said. This man went from he was too old to have kids to now he is worried the one we have has too much pressure? LOL so of course that comment sent me ovaries in overdrive. I am not sure why, other than I super duper love this man. He is very important to me. I am now back at the gym and no longer making excuses, I need to lose my extra weight. I am trying to prep and plan mentally. Then a couple nights ago, he verbally acknowledged that our daycare bill would be $1500/month for two kids. Then last night, he was like I am just gonna pack up my room (it's his hobby room for reloading and gun stuff) I asked him why? He said well where is the baby gonna go? I still have an IUD in! LOL so I guess men do get baby fever too?
