Whole milk allergy?


So my LO has had no reaction to dairy (yogurt, cheese and eggs) but we recently started giving bottles of whole milk consistently within the past week or so. The past 3 days she has scaly red bumps on her body (mostly her back). At first I thought it was dry skin but now I’m wondering if she’s having a reaction to the whole milk? Anyone have this happen? Do I try almond milk?
