Let me tell you my experience. My twin boys are 3 years and 4 months old and I work full time. For me it is impossible to take two babies with only one helper. I moved back to my 99's house and one maid together with 99 took care of them during the day time and I rushed back home right after work. The first two years was the most difficult and busy time expecially on Sun. when my maid was on hoilday. So I suggested you to get help from your Mom and 99 together with one maid.
