Toddler calls every woman mommy

Is this normal? Lol. Like we go to the library and she will be playing fine and then completely ignore me, go up to another mom and say "mommy help, follow me" and tries to take their hand💀💀💀 I feel so dumb for it hurting my feelings LMAO. I'm like "hey, mommy is right here, babe what do you need?" Like I pay attention to her, play with her if other kiddos aren't, honestly I probably hover way too much, and I'm never on my phone when we are at the library so I just don't understand why she does this. It's always in the play area where all the kids and parents are. The mother she did this to today just looked at me like wth.... It might be silly but it makes me feel like she must think I'm a horrible mother or something, and obviously she doesn't have the capacity to think like that, she's 2. Anyway. Anyone else deal with this?

EDIT: Thank you all for the comments! I've never spent a bunch of time with or around toddlers before my own, and have never seen other kiddos do this, so I honestly was like hmmm this is weird lol.
