toddler with allergies 🤭😷🤧

any mommies have toddlers with seasonal allergies? my little one has them so bad he needs to take zyrtec every day. I hate giving it to him because hes so drowsy. Is there any natural remedies yall would recommend I try? the pic of him on the door is his little swollen face without the allergy medication the one below it is how he looks when he takes it every day
