how about your parents? aunties ?are they able to take care of your baby?
maybe you might want to get nanny or put baby @ infant care..infant care might be abit expensive..but its better than havin a stranger in your house and the maid gotta work for quite alot of people in the household
you are right in your stand..having a maid will be the start to every issue...dont need to take on this additional burden on yourselves..
being a freeloader, your sister In law might change her mind about letting the maid touch her baby at the end of the day..and treat the maid as hers..and you have to pay for the maid and put up with her nonsense
