Little one has the flu momma pregnant

Hey everyone just wanted to reach out for some advice tips or tricks , My soon to be 5 year old has the flu 😷 since Monday 8/26 I didn’t find out till yesterday Tuesday since he had no other symptom besides a fever I thought regular cold or maybe throat fever he gets those as did I as a kid , I’ve been keeping him in his room he’s such a good boy I explain to him he’s sick and I can’t be around him but obviously I do at some point to feed him bathe him give him medicine and take his temperature I’ve used hand sanitizer every time I’ve touched him and I walk around spraying the house and everything with Lysol , I’m 37 weeks pregnant I have been taken vitamin C in hopes it gives me a little boost any tips or tricks to not getting the flu from him
