I think it's really depend on your economic situation and your feeling....
I never expect that I will be a full time mama before..... But I am totally changed after my bb came into my life, I hired a maid before but I really don't like her to touch my bb ( it is so staight! I don't have this kind of feeling when my mother hold my bb) I keep crying when I started to work and I know I must take care of my bb, otherwise I will be crazy!!!
But economic reason is a very important point to concern with.... it will be a pressure in a family, It will bring unhappiness and stress to you.... Remember, your bb can feel it, they are amusing, Happy Mom----- happy BB!!!
