The NHS advises going to sleep on your side from 28 weeks of pregnancy. A pillow helps you stay there, but if you wake on your back, just turn onto your side again.
Questions about pregnancy pillows
When should I start using a pregnancy pillow?
Whenever you start to feel uncomfortable, often in the second trimester. From 28 weeks the NHS advises going to sleep on your side, and a pregnancy pillow makes that easier.
Is a U or C pregnancy pillow better?
A U-shaped pillow supports both sides so you can turn over without moving it, but it takes a lot of bed. A C-shaped pillow is smaller and supports your back on one side and your front on the other.
Can I use a pregnancy pillow after the birth?
Yes, many people use it for support while feeding. Never let a baby sleep on or next to one.
