The short answer

On your side, left or right.

From 28 weeks of pregnancy the safest position to go to sleep is on your side, left or right. If you wake up on your back, do not panic, just settle back onto your side. That is the whole rule, and a pillow at your back makes it an easy one to keep.

What's going on

One habit at bedtime, not a night-long test.

Late pregnancy sleep is hard enough without a list of rules, so it helps that the guidance here comes down to a single habit in the moment you turn off the light. The reviewed wording below is the full picture, including the part almost every parent asks about: what happens if you wake up flat on your back at 4 a.m.

Notice the wording is about the position you settle into as you fall asleep. Bodies move at night, and the guidance expects that. Waking up on your back is your cue to roll back over, nothing more.

When to call

If something feels wrong.

This page is education, not diagnosis. If something feels wrong, call your pediatrician (or your OB for your own body). In an emergency in the US, call 911.

Tonight's small action

One pillow, placed on purpose.

Tonight, before you turn off the light, wedge a firm pillow behind your back as you settle onto your side. It takes thirty seconds, and it gives your body a gentle nudge toward staying put. If you wake up on your back anyway, remember the guidance: no panic, just roll back to your side.

Keep going

Where to next.
