Awww sweetie, I get the excitement but honestly tak semestinya kena beli special pillow untuk dengar zikir lah! A few of us tried playing Quran recitations through regular speakers or even YouTube videos free je, and our babies respond just the same, the important thing is consistency and the calm energy you create, bukan the product. I'm all for good sleep during pregnancy (God knows we need it!), tapi if zikir helps you relax, that's the real magic happening, mama!
