Bries first ear infection

We have been worried she had an infection for a few days but weren't sure because she has never had one. She would laugh and play like normal, the only things we noticed were she would loose her balance, and occasionally pull at her ear. Some nights she would sleep great and some like last night she was up crying. So today we took her to Dr Burton and he determined she had an infection and prescribed antibiotics. Poor girl I feel bad we didn't take her earlier she is so tough. She has been pretty funny lately she tries to put on her socks and shirt, feeds her dolly and dresses her rubber ducky in clothes.
