I think Carang has got the right idea. If you find yourself struggling a lot, be it with guilt, lack of time for your child, it's worth rethinking your career, especially in the first few years of their life.
I understand that not everyone can, for financial reasons but if you don't need to work to support you and your family why miss out on those precious years when our kids love us unconditionally?! Plenty of time to work when they start to know better.
I run my own business, working from home 3 days a week and going into the office the remaining 2. It's perfect. Absolutely no guilt.
