I preffered to restrict my students to full stop landings for the first 2 hours of circuit consolodation. Hour 3 would involve touch and go's.
A T&G is not that much extra pressure and not more than that involved in doing a go around which is obviously a madatory competency.
Nonetheless your first solo hours are full of adrenalin, elation, fear and fun. It often makes best practice to have your student slow things down by full stops, backtracks and takeoffs. At worst it costs him some time in the air but at best it lets him sharpen his ground handling and checklist skills and allows time for the adrenalin to ebb.
PIO is the biggest hazard on first solo sessions.
At the end of the day its a decision taken by the CFI and your instructor. Trust them.
