There are advantages and disadvantages to any spacing you might have.
My brother and I are 8 years apart and I was a lonely only for a long time.
My kiddoes on the other hand are quite close in age...13 months apart, 19 months apart, 16 months apart, 2 weeks less than 2 years apart, and one month less than 4 years between youngest son and DD. One month and 10 years to the day between oldest and youngest.
When DD got to Jr High I said if I can survive 3 boys in Jr High at the same time, surely I can survive one daughter! And I did...sanity was optional at all times!
