We have about 150 glow in the dark stars on the ceiling, hanging and flat(yes I am an idiot it only took 2 hours to get them all up) It actually helps my DD4 fall asleep . She just stares up at them till her eyes glaze over,so I would think the PJ's would have the same effect
BTW...the stars look really cool if I do say so myself...it is neat when the heater comes on and all the hanging stars twirl and twinkle. LOL
