I’d like “it” to be…

I would love to have another child, but I’d like it to be in a stable relationship.
I’m not sure about what “it” means in the above sentence.
Is she saying that she wants to have another child only when she is in a stable relationship, or that she is now in a stable relationship and she doesn’t want to break it by having another child?

The first -- she wants to have a child when she is in a stable relationship. "It" replaces "to have another child", so the second clause reads: "I'd like to have another child [when I am] in a stable relationship." If she meant the latter, she would have had to use a completely different construction: "...but I don't want it to endanger my relationship."

Thank you very much, rewboss!
