Hi, thinking of getting DS (17 months Old) a pillow for his cot. I'm hoping it will help him stay asleep in there as he constantly ends up in our bed. I'm just worried if he's too young for one and also where to get one from? Tbh Im ready to try anything as he just won't stay in his cot anymore and DH is sickk of sleeping on the sofa 🙈 any recommendations?
