It may seem like rather a strange product but the pillow here is so versatile you would miss it in a second were you not to have it. It is nice in the way that it can take the form of the baby and be wedged in place so you have more control over feeding for example.
BUT and here is the cool thing, it is for use before the birth as well- not just postpartum. My partner is always complaining that her legs go dead when daughter to be lays on mums nerves (dauhjter gets on mums nerves!). This pillow can aid with such sleeping issues.
Post natal the pillow can be used for many years after, in the early times it can support baby while seated on the floor aiding in core stability. Supervision is of course necessary as normal.
