You need more than a teaching degree or be a mother to teach childcare - in most establishments. What you lack is long-term experience and/or an NVQ3. Either, seek out courses where you can gain an NVQ3, or look at other options. What springs to mind is the Foundation departments/ Learner Support bases. Your degree might come in very useful to those moving from P scales to KS, or still working at KS2, even though they are over 16.
