i really don't know how to choose, it is the same problem to me too.
i definitely love my baby, that's why i quited my job to be a full time mother. however, after 10 months, i found that it is not easy to be a full time mother. it requires endless work and never ending love, but sometimes i feel so confuse, i am not sure i am a qualitified full mother or not. i still think of my working life:earn money for myself, i don't need to wait for my husband after work, i have lots of friends,and most important, i have my own space and my own life. being a full time mother means i need to give up my life totally, at least at this stage.
sometimes i feel so lonely as no one can share what i feel and what i think, even my husband cannot. however, everytime when i see my baby, i feel so happy as she is so fond of me, she needs me every single minute, that makes me think at least someone in this world make me so important, thought it may not last long....as she grows up, she has her own life, what's left for me? i am not so sure.
however, at least at this stage, i decided not to think too much, just give my best to my beloved, my daughter. if some day i have an opportunity to go back to the working world, i will work again if i want to.
my advice to you is : just follow your heart. if you found yourself cannot leave your baby at home, than try your best to be a full time mother; if you really cannot stand stay at home all day, than back to work. this is your life, you have the right to choose what you want. of course, i understand it is difficult to choose, for i feel so confuse too.
