my MIL takes care of my husband’s sister kid, his niece. she came to stay with us to take care of baby for a month so she had to bring the niece .

the niece literally can’t take the word no. Never says please or thank you , NOTORIOUSLY interpolating conversations (in person and on phone). The minute and i mean very minute grandma starts talking .., all you hear is .” grandma, grandma .” she won’t stop until grandma responds and will keep interrupting if she doesnt get what she wants which is often to type show names into the youtube app.

sooo, i have an 11-year -old that is not my husband’s biological kid (just an FYI)

the little girl is very bossy with my daughter which initially i just told her to ignore because she’s a baby. but she will literally see my daughter reading a magazine... come up and say she wants it, my daughter will say No and she will start crying to her grandma who will offer her something else to make her stop crying.

Every time i leave the house. i feel like grandma sort of “checks” my kid. for example, today after the magazine situation above occurred , my daughter was eating chips and the kid asked. she gave her 1 when she asked (impolitely ) and when she asked for another my kid said no. the little kid ran to grandma to tell her, grandma sort of brushed off ... so she came to tell me and i said “sometimes you can hear no.”

so i’m walking out door and grandma tells me that the kid asked my kid for some and she gave her 1. i said “well, she can hear no sometimes” and left

my daughter tells me when i left grandma (step grandma ) said to her “how do you expect the kid to share with you if you don’t share with her ? will you treat you lil brother this way too?”

so i’m angry because this isn’t the first instance in which she “ checked my kid,” and she NEVER reprimands the kid , her biological grandkid and she’s SUPER bratty, .

am i wrong ?

how would you feel?
