We live far away from family (both sides) and probably only see them a few times a year. LO1 used to have major anxiety around the grandparents but has been great with them in the last year or so since turning 3 years old.

My mom recently came to visit for a week, and the first two days were so good! I let her stay home on the second day and she spent most of the day with my mom while i was at the office. Because DH was away and i had to put LO2 to bed, i asked my mom to take her to gymnastics. Unfortunately, she got lost and she didn't really get to take part in the class for too long.

On the third day, my sister came to visit and things were okay...but LO1 was visibly unhappy to be around my mom. She started to become really rude to my mom, saying things like, "i'm going to checkmark you." (it's what the kids say at school when they don't like someone). She would make a face every time she came near her. Last night, she dragged my mom upstairs to do "exercises" but once LO turned on the ipad, she changed her mind and started looking at book review videos. Once my mom said that was enough, and she already watched 3, she said "i'm not going to be nice to you anymore" and walked out of the room. What the hell!

Her behaviour is so erratic - most of the time she doesn't want to talk to my mom or let her touch anything of hers, but once in a while she will be really sweet to her. But i honestly can't tell if she is only being nice so she can watch videos on her phone!

I got really mad at her over the weekend because i was trying to move the stroller out of the aisle at the farmer's market but because LO1 was trying to get away from my mom, she continued to block me from moving LO2's stroller.

I have tried to talk to her - asking whether she would like it if her friend yelled or wasn't nice to me, and how i would feel the same because her grandma is my mom.

I am beyond frustrated and hurt by her behaviour. My mom was just "oh, she's just a child - just let it be" and DH thinks it's normal kid behaviour (which is just bs since he gets upset when she doesn't want to talk to his parents). No one i know can relate because all of their kids see their grandparents all the time.

Any advice on how to address this?
