-The Modern Midwife, Marie Louise
Why is it important pregnant women don't sleep on their back?
"As your baby grows alongside the fluid around your baby and amazing placenta - the weight of your uterus increases. This can put pressure on major blood vessels and can reduce blood flow to the baby.
"Some pillows you can buy support you to remain in side laying position. Or encourage you to fall asleep in that position and research shows the position you fall asleep in is often the one in which you remain in for longest."
Is 13 weeks too early for pregnancy pillow?
No - marking the start of the second trimester, 13 weeks is a great time to start using a pregnancy pillow if you feel in need of extra support and comfort in bed. Our SnuzCurve tester actually recommended that the pillow be used 'from as early as possible' to give the user time to get used to its shape and the positioning it encourages.
