We wish to image fields containing more than 20 spectroscopically confirmed z>5 galaxies in the 3.6, 4.5, 5.8 and 8.0 micron bands. When combined with our existing extremely deep optical data on the fields we can determine the complete observed SEDs of the sources to 4.5 microns, and possibly to 8 microns. Using these SEDs we can determine approximate star formation histories for these sources. If they are shown to have undergone bursts or extended periods of star formation to z>10, then this gives strong support for an extended or multiple reionization of the Universe. Non-detections will mean that these sources are undergoing their first burst of star formation at z<6,and cannot have contributed to any very early period of reionization.
