Social visit in Macau

Hi, we are Singaporean traveling to Macau and China to stay with our relatives in both places for about 2 to 3 months with our Indonesian maid who is helping to take care of our little 2 years old boy. We may be traveling in and out Zhuhai and Macau frequently. How and which type of visa should we get for the maid?
Please advise and thank you.
