I think it is still not that late after the 2nd is come. My hubby and I have planned to have the 2nd first then when the 2nd is around 2, let him/her attend the full time nursery.
At that time, the boy is around k2, then I quite the job and be a full time mama + study master. I think it takes around 2 yrs to finish the master course.
Cherry:
Do you take 2 masters? what subject do you study?
