Strabismus Extropia

My daughter just turned 5 months and (both) her eyes always wandered outwards since she was born. It was a lot worse actually and has gotten better to a point where I forgot all about it. But now I am still noticing it constantly. Mainly when she “dazes” out or even when she is chewing on something for “stimulation” or discovery etc. I’ve mentioned this about three times to my doctor and she keeps saying to monitor it. I’m getting frustrated..if it doesn’t resolve by 6 months should I be concerned? ☹️
