Doesn’t want to lose me after baby

My husband and I have been together almost 2 years and got married September 2022 and today we were talking about having kids (we’re thinking about trying in 2025, we talked about it while dating and before marriage and we both said we want kids) and he said he’s nervous about it because he’s going to lose me to the baby. I understand it because sometimes I get nervous and a little sad when I think about it and realize it will no longer be just him and I. I get a little sad when I realize that I’m going to lose having him completely to myself and it just being us. Of course I’m going to be excited to start that next part of our lives when/if the time comes, but it’s been just the 2 of us for so long that I feel like I’ll miss that. Just being able to cuddle and go on random late night drives or spontaneous trips and just being able to spend time with each other in general. The whole dynamic will change in a few years and I don’t know if it’s wrong for me to say but it makes me a little sad and scared. Does this make me selfish? Has anyone else felt this way? Should I just not have kids because I would be a bad mother since I thought this? 😞
