Yes to having a baby or no to having a baby??

My husband told me last night while looking for a carseat for our toddler said "please dont get mad, but I want another baby." I was confused because I wanted another baby last year but he said no. I said "well your gonna have to wait because I already made up my mind to wait." Both of our kids will be going to school next year and now I'm just questioning myself if I'm mentally and physically ready for another kid.

I had my mind set in my 30s to have our last kid but now I'm not sure....like I will be 24 this year and now my head is just confused. My heart wants a baby but my mind is telling me no.
