Cuphead helps kids practice and improve the following skills:

Working Memory: Recalling and retaining information in our minds while working. 

Each boss in Cuphead is its own exercise in difficulty, meaning the player needs to recognize their patterns of attack and keep that information in their head while constantly moving and shooting to avoid being hit. Cuphead only gets three measly hit points so it is essential that the player avoids getting hit by recognizing when a certain attack or projectile will be coming their way. Players who struggle with working memory may find that they need to try each boss fight several times before they are able to decipher the patterns and avoid taking too much damage. 

Flexibility: Adapting and adjusting to changing conditions and expectations.

Because each boss battle is unique in their own way, the player needs to constantly adapt their method of fighting in order to be successful. Even if they know the pattern in which each boss sends out their attacks, they still need to be able to adjust to moving away from projectiles, jumping onto moving platforms and avoiding taking damage all while dealing damage to the enemy. Players who struggle with flexibility may find that they need to battle the same boss several times because they have gotten stuck in one type of fighting style.
