Yes,she parented, and we had very little. She also never had a boyfriend and devoted herself to our care.
When I got married and had kids myself I looked back in wonder at what she did.
Sounds like she did a lot the same thing I did. I worked second shift, so I could be home with my son, and the time away was mostly sleep time. Even read to him on cassette tapes so he could still have that even when I wasn't home. I too, delayed my own personal life until he was older.
