Is it weird?

So I just had another baby 3 months ago and am fully breastfeeding and pumping ! Only thing is my little man won’t take a bottle so I have over 600 oz of breastmilk in my freezer. So my real question is would it be weird to give my son (19 months old ) my breast milk in his sippy cup instead of soy milk (he can’t have vitamin D milk because he pukes ! )

I don’t want it to go to waist and if it would benefit my son that would be a plus!
