Section 5.1 of the CourseNotes demonstrates how to fit such a model. A  
limitation of MCMCglmm if there are >2 time points is that there will  
probably be temporal auto-correlation which will not be accounted for  
by simply fitting subject as a random effect.  ASReml would allow you  
to include temporal auto-correlation if needed, and possibly lme.
