In Who's Your Daddy?!, one player takes on the role of a baby, while the other plays as the father. The baby's objective is to explore the house and find ways to harm themselves, while the father's goal is to prevent the baby from getting into danger.

As the baby, you need to navigate your surroundings quickly. Look for harmful items like cleaning products or electrical outlets. Utilize the environment, such as crawling or climbing, to reach these dangers while keeping an eye on your dad's movements.

As the father, focus on staying close to the baby. Lock up dangerous items, keep the baby in sight, and anticipate their moves. Use tools like the baby monitor to track their actions and act swiftly to prevent harm.

The game features several items, such as batteries, cleaning supplies, and sharp objects, which can be harmful to the baby. Understanding each item's location and function is crucial. For example, batteries can be swallowed, while the father also has access to tools to protect the baby, like the first-aid kit.

Open the main menu. 2. Choose the 'Customize' option. 3. Select your preferred character features. 4. Save changes before exiting.
