Should we go for #3? Tips? Experiences?

We had agreed upon 3 kids for years but now my husband says he’s content with our boy and girl. My heart still wants 3. But my mind sees his point of view at times of getting more time in our lives back as the kids get bigger with more independence it would start things over again. But our kids are 3 and 1 and I don’t want to wait for a large gap and I also don’t want to wait until I am older. The 3rd would end up having to share a room with a sibling which I don’t think is a big deal but my husband said it will cause issues. We both see each others point of view and are not planning on trying (if we do) for a bit longer. Curious other people’s experiences or advice? I also hear from family that odd numbers makes it harder and there is always an odd man out or the dreaded “middle child” syndrome. I love being a mom and would love to love on 1 more baby in my life but also would be content with my 2 beautiful babies.
