Love love love this item and always one of my number one items I recommend to new moms! We’ve used this sound machine since my first was a born and he’s still using it today at 4 years old! Love it for travel in the car and vacations! The back up battery is great on stormy nights! Give sis peace of mind knowing our kids can sleep anywhere we go! LTKBump LTKGiftGuide LTKBaby
