Is It To Be Concerned About Infection In Ear Of A Child?

Hi. I have a 22month old that was showing signs of an ear infection yesterday mid afternoon, pulling and hitting ear accompanied with extreme fussyness. I administered 5ml of ibuprofen and she settled down enough to take a nap. After her nap she was her same old self. Fast forward to today she has acted completely normal no complaints. Then this evening I was buckling her into her car seat when I caught a glempce of her right ear (same ear as yesterday) and she had an enormous amount of yellow/greenish drainage. Obviously there is infection and im aware it needs antibiotics which leads to my questions, 1. Can I wait till the dr office is open and take her in tomorrow or do I need to go in tonight? No fever, no complaints, the ear isnt even red or warm to the touch. And 2. Should I press the need for tubes? This is only her 3 ear infection, but ive never seen one like this befeore and I have seen a ton(mother of 4 under 6 here, one that had 27 ear infections in 2 years with 4 sets of tube s and finally an adnoidectomy and reconstructio)
