Do you make your child share?

So I’ll start by saying I do try to get my daughter to take turns with toys when she’s around other children. But I don’t necessarily make her share her toys with others especially specific items that she’s really attached to

I take my daughter to work with me. I drive school bus and since she’s on the bus for 2 hours in the morning and then another 2 hours in the afternoon we got her a tablet about a year ago that she watches kid movies and videos on. In between routes we go in my coworker/friends bus (my only time to talk to adults lol) who also has a daughter the same age. Her daughter (who has her own tablet) is always trying to take my daughters tablet or puts her face really close and tries to watch over her shoulder. Which my daughter doesn’t like so she moves away which causes the other little girl to get mad. And her mom will always say “you know she doesn’t share”. And I’m about ready to snap. If my kid doesn’t want to share her tablet or have your kid all up in her face she shouldn’t have to! As adults we don’t go up to another adult and say I’m gonna use your cellphone cuz you need to share her.

I’ve just been ignoring it but am about ready to say something to her about constantly saying how my kid refuses to share and making it seem like I have such a horrible child because she doesn’t want to share her tablet

Just trying to see if I’m wrong and the pregnancy hormones are making irrational lol or if I have a right to feel this way
