I went back to work when DD1 was 6 months old. She was in childcare until she went to 'real' kinder (not a childcare centre. I found she really thrived at childcare.
DS on the other hand didnt handle child care at all. I ended up stopping work and pulling him out until he went to kinder. He did much better being at home with me.
He is now in prep (first year of school) and is well socialised from his year at kinder.
Hope that helps x
