Oh my good god. It says this
The soft chimes of this Pregnancy Rattle will serenade and soothe as your little one prepares for a grand entrance into this world. After birth, gently shake the rattle, while together, as a reminder of more peaceful times for both of you. As each piece is made by hand, the chimes are unique to you and your baby.
Who the hell comes up with this stuff?! If someone tried shaking that at me during labour they'd have found it inserted somewhere uncomfortable!
