Template Sensor Updates when HAS Restarts - How to avoid this

Hey all, I have a template sensor that i use to track when the kid is asleep and then wakes up, but the issue im facing is the sensor updates the last triggered and timestamp when the home assistant restarts or when I have update template sensors. is there a way to add some code in the template to ignore these types of triggers?

Yes, probably. Share your current sensor configuration.

yeah that would have been good

- platform: template
      friendly_name: Beau Sleeping
      unique_id: Beau Sleeping
      icon_template: mdi:sleep
      value_template: >-
        {% if is_state('binary_sensor.beaus_bedroom_door_group', 'off') and
              is_state('switch.nodiee_sleep_machine_music_switch', 'on') and
              is_state('binary_sensor.beaus_bedroom_window_blind_contact_sensor', 'off') and
              is_state('light.beaus_bedroom_lights_group', 'off') and
              is_state('select.nodiee_sleep_machine_scene_select', 'Shusher') %}
          Is Sleeping
        {% else %}
          Woke Up
        {% endif %}
        timestamp: "{{ now().strftime('%d-%m-%y %H:%M:%S') }}"
        last_triggered: "{{ now().strftime('%d-%m-%y %H:%M:%S') }}"
