Ds wakes up in the night and has a drink of water. It is a non-leak cup so we put it next to him in bed, but most nights he loses it and I have to get up to help him find it
(or most annoying... "Mummy mummy I can't find my.....oh here it is!", when I am already at his bedside )
Would a glow in the dark thing work do you think? Or can you get glow in the dark indelible paint or something?
