I have 4 boy's ages almost 14, 13, 11,10. I did want 5 but I had complications with the last 2. I did not care what sex they were, I just love kids and wanted a big family. I would love to have been able to have the 5 one but it is not going to happen
My oldest sister has 3 ages are 18, 14.and a 1 year old! Oldest and youngest are girls. She had no problems with the age differences. Her older two help her out all the time! We did give her a baby shower because she did need new things for the baby!
Hope things go the way you want it!
