My baby grandma takes her stuff

So the few times I did bring my daughter to her dads grandma house I’d have big bows or head bands in my 2 year olds hair. My daughter asks for them & even at home when I try taking it off or it’s falling down and she thinks I’m taking it off she’ll make a fit. She keeps them in her hair. At her grandmas house she NEVER gets them back and her dad can’t find them supposedly. Me and her don’t have a good relationship nor speak the same language so I don’t bother texting or calling her about it but it’s WEIRD AF!!! And it’s getting me so mad… I asked her dad about it today and he just ignores me and blocked my number so I called a bunch of times because they’re just sooo annoying and toxic!!! 🥴☹️ idk just needed to vent..
