How long should you be in a relationship with someone before you have a child

I’m not rushing at all, I don’t mind waiting but baby fever is killing meeee. As of now we’ve mutually decided on waiting five years before trying to have a baby, the only thing is my son will be 10 by then, I don’t want to feel like I’m basically restarting when it comes to raising kids. My boyfriend said him being 10 works out great because my son will be old enough to be more hands on with baby which is true but like I said looking at it now I feel like I’ll be starting completely over. Maybe I won’t feel that way when that time comes but idk.😬

**Me and my ex were only together for a year when I got pregnant with our son. Which honestly I was okay with but I just don’t know. I know waiting is the best thing but at the same time the more I think about it the more I don’t want to wait.
