How can I stop feeling of wanting a girl?

I have 2 beautiful healthy boys which I would never change the world for. They are my life and I adore them however how can I stop the feeling of also desperately wanting a daughter? Anyone else feel like this? Is it normal? I think our family is complete. I can't really have another baby in hope it's a girl. I would equally love another boy but if I knew my third was a boy I would stop at 2 as just means we can have a better quality of life.
