Well, breastfeeding has been the norm among agriculturalists as
well as paleolithic people until rather recently, so that
wouldn't account for a change in birth rate during the paleo-neo
transition.  I am aware that a diet that is rather sharply
restricted in calories can suppress ovulation, probably by
reducing body fat to extremely low levels, but I am not aware
that the typical paleodiet is so hypocaloric.
