I worked in child care and as a nanny before and after I had my DD.
Its definatley do-able, but i loved loved loved it before having DD, and after her I didn't like spending that time with other peoples kids anymore.
I'd take DD with me 2 days, and she was in day care 2 days, but it was pretty hard, compared to when i did if before having kids.
I felt like all i did 24/7 was deal with kids, cook, clean blah blah blah and it all got too much. I could have kept doing it, but in the end i chose to study and start a new career.

If for the financial side it would be beneficial, then maybe ask about a trial period for 3 months to see if it works for you and your family befire making a desicion

Good luck!
