One thing I notice about these shows is that often the obvious issue is a couple with too many kids close together and the parents are overwhelmed.

Some may view that "too many" as just right.  We have three children approximately two years apart.  So far, it's working very well with us.  I have relatives with similar mixes.  In my case, I was kind of in a use it or lose it place regarding fertility due to endometriosis.  We had to ttc as soon as possible in between children or risk my losing my one good tube.  When deciding whether to go for #3 it came down to the thought that I would regret the child I didn't have more than the one I may have.  While I'm pretty certain we're done, I don't think we'd deserve judgment about our number of children or spacing from anyone.
