So I bought one of this blue night lights for Pogo before I realized they were bad/ unnecessary and I lost the receipt so im stuck with it. I was wondering though if it was fine for a bit of warmth for him if I set it up away the right height beside me next to my chair when I settle down at night to watch tv? I thought I read somewhere that the light might be bad for his eyes. But I also feel like I read that the light just interferes with sleep schedule?
