Same advice, live in maid is the best option.
I had 2 Sri Lankans before, they were really good with the kids, but one started to steal alcohol and a lot of things started to disappear, she was sent back home.
The other one, very hard worker, I was paying her 2,000dhs a month which is good money for a Sri Lankan + food vacations, medical, etc. in a family of 3, everything was great until we found out she was working illegally for another family on Fridays and in the evenings on her free time, she also wanted to bring her husband to live with us, so too many problems, I didn't renew her visa.
Now we have a Filipina 36 years old with 3 own kids in manila, man she is good, she has being with us for 6 months, not a single complain on her, she cooks, she is great with my kids, my wife loves her, I couldn't ask for someone better, but is difficult to get a good one in Dubai, be careful and good luck!
