Did you plan it that way?
My oldest 2 are 2 1/2 years apart but I wanted them a few months closer...didnt happen. My youngest is 4 years younger than my 2nd child. Planned and unplanned...I wanted to wait because my daughter was a handful and I couldnt handle a baby and her...then I was ready but it didnt happen for awhile.
So mine are 17, 15 and 11.
