We see the montage of Sasuke training to perfect the fireball jutsu every day, training so hard he collapsed from exhaustion and rehearsing the fireball jutsu so frequently it burns his face.
Fugaku seemed mostly concerned with results, only being interested when Sasuke finally perfects the fireball Jutsu, not the steps it took Sasuke to get there. But Mikoto doesn't care about results, she cares about the journey. Mikoto is involved neither with the difficult start of Sasuke's training nor the end when he achieves success. Mikoto isn't there when Sasuke performs his fireball jutsu successfully for the first time, and Sasuke doesn't seek to show his mom his new trick either.
We only see Mikoto involved in the middle of Sasuke's fireball training, as she is the only one to notice the burns on her younger son's cheeks and she tends to his injuries.
Mikoto is also the one to tell Sasuke not to push himself too hard and to take time to rest every now and then. Mikoto is aware of how much hard work her son puts into learning the new jutsu, and she is a caring presence to his current struggle, not oblivious to his present struggles.
