Sick?😭

How many times have your babies gotten sick? My baby never got sick at all until he turned 6 months old. He just turned 8 months a few days ago and it looks like he’s sick again with his THIRD cold 😰 is this normal? 3 colds in 2 months? I’ve got to be honest I’m a little frustrated because I take so many precautions with keeping him healthy and every single time he gets sick I get sick and I just can’t be getting sick every month 😭😭😭

Edited to add I’m a SAHM so he doesn’t go to daycare. And yes I exclusively breastfeed!
