the two boys are both her bosses, she can't be like that. Besides, she seems to be the boss in your house rather than you, by judging on the tone when she talked to you.
Tell her directly that you find her reactions being inappropriate and you get annoyed. All your boys and you are her bosses and it's reasonable enough to ask the employee to listen to employer's order.
No need to be afraid of her. If she continues to be rude to you and your big boy, it should be time to look for a replacement coz you can't control over her any more.
seems like your maid thinks she is the mom of 細佬~~ well, I guess you should also spend equal time in taking care of both 哥哥 & 細佬 at the same time instead of just focusing on 哥哥 and leave 細佬 to the maid lor... in that case, your maid can also build up a close relationship with 哥哥 ...
well, i have a 6-month mui mui and a 2-year old哥哥... I will try to balance out the time in taking care of them.. so that my maid know I care both and she should also be able to take care both lor (everyone knows 2-year old is much harder to control while the 6-month old is much easier)
your maid's action could also caused by seeing you focus on 哥哥 most .. and she feels 細佬 is being left out by you.. .and therefore, she will be more 偏心 on 細佬 coz' she thinks you 偏心 on 哥哥 mar....
