My maid is taking care of two kids, one 2 years old and the other 3 months. She can handle the basic housework at the same time. She doesn't need to go to the market as I'll buy the food for her to cook. I think taking care of a newborn is not particularly difficult as the baby just sleeps and eats in general. When the little one starts to crawl or walk, more attention will be required. So far, my maid doesn't complain. As she says, every day is a busy day but not a hard day.
My maid also take care 2 kids. One is 1.5 yrs old and one is 4.5 yrs old. She also said very busy and tired. i just request her to keep my kids in safety is enough. It really depends on she is willing to do or not .she is helping me the third year.
