Baby smelling breast milk?

Da

So I work at a daycare in the nursery and there is this baby (who’s breast fed) and she’s been “attacking” my boobs anytime I hold her she trying grab at them and “bite”. I’m 29w and another worker said she’s probably smelling your breast milk but it’s too early for that, right? I’m the only teacher she does this too but I’m also the only one pregnant.
