exactly the same case. so i fired the maid when i'm preg. however the new one is so green. she doesn't know what to do every day. even for daily routine. really "waste gas" to re-teach her every day for the same thing.
so we will fire her this month later. cuz' she is really can't manage to take care of 2 kids!!!
stupid might be better than smart. but toooooooo stupid can be a BIG problem.
