At the top of the main screen, you'll find a small pink bar displaying your baby macaw's age in days. This lets you keep track of how old your little one is and see when their next milestone will happen.
You can skip game time to get closer and closer to these milestones by tapping the "+" button. A pop-up menu will appear with a slider in the middle'-slide your finger to decide how many days you want to skip, then tap the confirm button below to start the time skip. Keep in mind that skipping time won't affect your little guy's needs, but it does cost crystals, so use it wisely!
