$2000 is not much if you can afford hiring a maid at home.
To me, I give 50% of my salary before and after marriage. I haven't increase the amount although my mum is now taking care my daughter and pay for the maid. I really thanks for my mother and I even asked my daughter to love her more than me because she is the ones who take care of her most of the time
My mother also has personal life and I will not inforce her to take care of my daughter all the time if she has other appointment and I will sometimes buy some household necessities, drinks, etc for her.... show care to her is what she really appreciate and I really love her much!
