I’m 38 next year

Relationship has its ups and downs especially since having our baby (now 2years old)

I struggled with little support from partner (even thou we live together)

He finally has a job (hopefully he will stick at it)

I’m very insecure and lost all self confidence since baby.

Would I be mad or selfish to have another baby?

For some reason I can’t stop thinking about having another baby a sibling for my son.

I think I know I would be left to deal with everything like now but I can’t shake the urge but fear another baby would break us and possibly me mentally.

But I’m getting too old to wait any longer (35 was always my cut off age for having babies).

Opinions?
