From Earth to the Moon - A 3-Year-Old's Journey with MLS 5.5G

[Determined]

Which format is he listening to?

I feel like he'd be able to listen to the masked track or hybrid track if I could start it immediately as he goes to bed. Since I'm the one who puts him to bed the majority of the time, and don't want to risk the exposure to myself (I'm running DMSI 3.1), I set an empty/silent track for 3 hours that is then followed by 5 ultrasonic loops of MLS. Another reason I did that was to make sure he's good and asleep before the sub plays, as I've seen some reports of users who are experiencing trouble sleeping while listening to MLS. I figure if his room is silent, and then a trickling stream or ocean surf sound suddenly is errupting 3 hours into a 3-year-old's sleep, it may not go over well.

Very well thought out. Clever solution to the sleeping problem as well. Your sons going to be a beast
