Mums, what is the longest gap you would have from your last child to your next? I have a 12 yr-old. The gap seems way too big for me to have another baby now. Any opinion on this?

I have a 6 year gap with my younger brother and a 16 year gap with my younger sister. We are able to live amicably and help each other out whenever needed. When my siblings were younger I helped out a lot with caretaking and teaching them school stuff. I think big age gaps are cool and relieves the burden of parents.
