Go for it and have all the fun you want making them. Make a couple extras while you are at it if you feel the urge. I know I so wanted to ask my kids if or when they planned on having a family. To my surprise family came first for one and about 5 years after for the second. I was prepared for neither. Of course I met the challenge but felt rushed. I always wished I had not had the pressure on me. You never know a niece or nephew or even a friend may be having a child into their families. They won't be wasted and do it while your vision is healthy.
