sounds ok . Maybe you can try out your method first and ask the maid to open up to you if she cannot cope? I have a few friends who ordered tingkat too, just that need to find a good caterer. I've heard from some that they send their child to half day IFC and ask the maid to fetch.
For me, my maid used to take care of my son while my daughter goes to full day childcare. we didn't picked on the housework & the dinner too.. it all went ok. until my maid asked to go back to her family. My mum helped to take care of my son for me until we got another maid.
Now both my kids (2y/o & 3y/o) goes to the childcare. I'm also planning for my current maid to look after my daughter too while my son goes to the childcare still. I'm switching my daughter to morning session kindergarten. For dinner~usually I will prepare the ingredients for next day's dinner before I sleep or wake up earlier to prepare stew before going work.
Jia yous! & gratz on your new bundle of joy
