Just bought 3 packs of luminous stars from Popular bookstore... In fact I got this idea long long ago, when little Alex is still little momo. That time she is still a baby so she might not be able to appreciate the stars, unlike now.
While she is still in school, I pasted the stars all over the ceiling. So when she is home, I took her by the hand and switch off the lights. Her face is filled with grins and I told her to lie on the mattress for a nicer view.
See the big star below the smaller star? Yeah, that's Papa star and Momo star...
