How long before your baby stopped getting sick EVERY WEEK from daycare!?

I can’t take anymore! My daughter has been in daycare since she was 7.5 months old. She’s 15 months old now and I swear there hasn’t been a period where she was well for a week since. It’s constant! Constant ear infections, colds, strep, herpangina. She seems to have a chronic cough. Shes had tubes placed and still has horrible ear infections. She’s been on so many antibiotics I’ve lost track. I’m exhausted!! Doctor says it’s what happens when kids are in daycare. When does this end!? Has anyone else been through this? 😰
