if u have this requirement, then you should also talk more to the maid when interviewing her to assess her ability in spoken english. By my experience, most of them the standards of english is no good and some have the undesirble accent of Philippino!!!
I want my kids to have good english accent and talk fluently and correctly.
for my case, I send my kids to English playgroups with good native English speaking teachers. I think learning second language, you should have a good start in terms of accent etc. Also, I would buy DVD, CD of good quality for my kids to watch and listen at home.
I think it depends on the English standard of your Phil. maid. If you want to achieve this task, you should find a maid with a good English accent. That's help! But you still need to provide a good environment for him.
For my case, my maid has a proper English accent. And start from new born, we talk to him with English most of the time. Also, he watch the English program & cartoon only. So he now get use to speak in English. He only start to speak in proper Cantonese after he go to KG this year.
