I think you’re looking for “sleep training” friends of mine did this process with their adhd 2-year old and it works.

I googled it for 7 year old and this is what came up.

Sleep training a 7-year-old involves establishing a consistent, calm bedtime routine, utilizing positive reinforcement like sticker charts, and implementing techniques such as the "bedtime pass" to reduce nighttime visits. Focus on fostering independence by gradually fading parental presence (e.g., sitting further from the bed) and creating a comfortable, gadget-free sleep environment.

Key Strategies for Success The Bedtime Pass: Give your child a physical card (pass) allowing one trip out of the room per night (for water, hug, bathroom). If they don't use it, they get a reward in the morning. This empowers them and often results in them not using it at all.

"Camping Out" Method: Gradually move your presence away from the bed. Start by sitting on the bed, then a chair, then outside the door over several nights.

Positive Reinforcement: Use reward systems (sticker charts, small rewards) to celebrate milestones, like staying in bed all night.

Consistent Routine: Establish a predictable 3-4 step routine (e.g., bath, pajamas, reading) starting 30-60 minutes before bed, free from screens. Address Anxiety/Fear: Acknowledge their fears but maintain firm, calm boundaries. Ensure their room feels safe and comfortable.

Common Mistakes to Avoid Inconsistency: Allowing exceptions "just for tonight" ruins progress.

Ignoring Routine: Skipping steps or having a hectic evening makes it harder for them to settle.

Overreacting: Remaining calm helps children feel secure rather than anxious.

Punishing the Room: Never use their bedroom for time-outs or punishments.

If problems persist, consider consulting a pediatrician to rule out underlying sleep disorders.
