Ear tube parents!! Questions!!

My daughter will be 3 February 17th. She had ear tubes placed and adenoids removed 9/22/24.Ever since, we noticed so much drainage. The tubes are definitely doing their part- she can hear and talk so much better now. Shes honestly a whole new kid. Shes even singing now. Anyway, We do drops when it’s draining a lot but Today it was superrrrrrr thick and dark green, honestly like hard snot!!! I called her ENT they say let’s start the drops and we can see you next week Thursday. Has anyone experienced this with ear tubes before ? I was doing some reading I’ve seen MRSA infection come up a few times.. im so worried now. Overall she’s been great besides we got hit with the Flu on Christmas. And just are getting over a stomach bug. She doesn’t seem to be in any pain whatsoever. No fever. Appetite is great. Just the snot like discharge that’s concerning me.
