I've had a 2.5 year gap between each of my kids. DS is my last and I am really enjoying him without the pressure of a newborn as well. I sort of feel the other two missed out on a bit at this age because the younger siblings were quite clingy fussy babies who demanded most of my attention.
However after 7 years of intense parenting of young kids I am pleased to be "coming out the other side" and onto the next phase (which I am sure will hold some new challenges too)
Pros and cons for whatever you choose.
