How to boost your immune system ?

Kayley

I’m new to this group so apologies if it’s been asked a lot but my kiddo is sick CONSTANTLY (2 yo) and every time he’s sick I get sick and I’m just so sick of being sick ha I must have a weak immune system. When he is sick I start taking zinc and airborne or emergenC but it doesn’t seem to work so I’m thinking I need to incorporate something in my daily routine to help boost my immune system. I’m open to any and all ideas, natural, vitamins, etc.
