I'm Secondary trained, but have worked top-end Juniors. Friends of mine were, however, Infant school teachers. The tales they gave me of children unable to dress themselves, even toilet themselves, were horrendous. This sort of level does not require a Graduate Level qualification - any sensible mum or dad could cope.
I don't think that most teaching requires a degree. My generation did 3 yrs. training and received a Teaching Certificate from the local University. We were competent, practical, intelligent teachers. If one wished one could do a 4th year at the university for a degree in Education. Subject specialism courses ensured enough knowledge to teach up to and including 'A'level (in the case of Secondary Teachers) - I assume up to the old 11+ standard for Junior trained..
Probably sounds rubbish to today's fixated-on-degrees generation - but these were the people who got you to your degree...think on!
