I find my working hours are too long and is causing my LO to prefer my mum or helper over me. What other jobs can i consider to seize the golden childhood time with my baby? Has anyone thought of this question?

Any way you could speak to your boss for a more flexible working schedule or changing to a part-time scheme? If you can work something out such that you can work from home, it may be an option to consider. Otherwise, you can look at your current family expenditure and see if you could make any lifestyle changes to allow you to be a SAHM.
