The most important thing that you should do is establish a routine, anonymous. You’ve just started a new journey, so it’s understandable that you may still be figuring out the balance between journeying and taking care of yourself and your team. As mundane as it sounds, that is actually one of the most challenging aspects of being on a trainer’s journey. However, routines enable you to be consistent when training your pokémon, especially when training them for day-to-day tasks.
While your other pokémon may adapt well with or without a schedule, it’s important to keep in mind that pokémon you catch later on in your journey may operate differently. You’ve just gotten a taste of that now with your panpour. So as restrictive as it may be for the pokémon that have adapted to a looser routine, you’ll want to adopt a stricter one until your panpour can effectively be trained to go to sleep when you do.
The first step in doing so is deciding when you’ll set up camp and dedicate yourself to doing it every night at exactly the same time. Always do it at exactly the time you’ve decided upon, rather than rely on a vague time marker (such as the setting of the sun) to do so. This will instill a sense of time on your panpour because you’re creating a consistent sense of hours on the road. (For that matter, always break camp at the exact same time each morning, even if you’ve woken up early and feel that the perfect conditions to train.)
Second, meals. Meals will likely be the other marker that will be of most interest to your panpour. Always feed all of your pokémon at the exact same time each day to reinforce the first time marker (that is, setting up or breaking camp). Follow this by creating other markers out of the things you also do every day. For example, if you have a specific training routine you do before or after setting out for the day, do it at the exact same time each day. Travel on the road for the exact same length of time. Change into your bed clothes and take care of your and your team’s hygiene at the exact same time. You likely get the idea from there.
Once you’ve decided upon times and dedicated yourself to your new schedule, the other thing you should do is apply rewards or discipline to your panpour for following or going against the routine, respectively. For every marker that your panpour adheres to, give him a treat. This can be a small snack for markers during the day, but at night, you may wish to give him affection immediately or extra food and praise in the morning. (Try to avoid giving him a snack too close to bedtime, as this may make him restless at night.) If, however, he does not stick to a marker, give him a stern verbal warning but be gentle at the same time. Never shout but instead explain to him in simple terms why he needs to follow routine. Eventually, he’ll associate following the markers with rewards and not following them with, well, a lack thereof. In any case, the more you reinforce those markers, the more your panpour will be able to follow them on his own, allowing him to understand when bedtime actually is.
Best of luck, anonymous!
