Mine also sleeps independently and won’t sleep if I’m in the room. I went to a birthday party recently and had no idea how to get him down. If I were at a hotel I’d have to put him down and literally go sit in the bathroom until he fell asleep or get him in the car and do a car nap 😭 maybe a walk w the stroller.
Can he not sleep in a travel cot wherever you are ? Maybe bring some portable black out blinds x
