Tips to not fall sick

Hi mamas, is there any tips you have for me to avoid falling sick while taking care of your sick baby. I find it ridiculous that I will fall sick everytime my baby is sick. I understand that while taking care of him, my chances of getting his flu is higher. But when I fall sick I don’t have the energy to care for him. And it’s harder for me to recover cause I can’t rest while I’m sick, cause I’m caring for a sick tiny human 🥲 And I’m afraid to take drowsy meds. Afraid I’ll sleep through baby’s cries at night. What do u guys do to avoid falling sick as well?
