I face a similar situation. My son is now 14 months, but I have to work from 8am - 6pm everyday (but I still need to work at nights after my baby sleeps on a few days weekly). Including the travelling hours, I need to be away from home for 12 hours everyday. I don't want to quit my work, and I don't want to neglect my son either.
To strike a balance between work and family, I'll try my best to accompany with my son during weekends. What I need to sacrify is my rest time and leisure time.
