S.S.
My children are spaced apart at the oldest and youngest level with 2 boys right in the middle. my daughter was 13, sons 5 1/2 and 7 when youngest son was born. the oldest and the youngest bonded when I brought him home from hospital. the other boys were enough older that he was a collosal pain in their butts lol until he got bigger. he is 14 now and very close to both the older boys. I wouldn't worry about the spacing but if you are maybe you want to have 2 more so they have company for each other lol
