^uhhh, i read it differently - being that she didn't want the maid OR her kid at the table.
and it seems to be more than just: "so i dont see anything wrong here. its not like u r giving up ur child for adoption. u r just having someone to keep them lil entertained n under supervision when u r busy or not around."
rather she thinks she too good to take care of any of her kid's needs. and the OP is annoyed that the girl herself comes from a background where she was 100% cared for by her mother.
i dunno wat kind of mom this lady is but moms r moms afterall. no matter how much a caretaker is doing they do have their own roles in their kid's life so just by hiring a nanny u r not giving up ur whole responsibility. esp when this nanny herself is 10 yrs old. i dont think she was mad at her kid at the table but nanny with her kids at the table. if i see it correct. may be she wanted the nanny to feed the kid but not at the table with her n her hubby.
