Pregnancy insomnia is extremely common, and worth naming clearly: it's not a sign you're doing something wrong, and it isn't always fixable with the usual sleep advice.
What's actually driving it varies by trimester. Hormonal shifts, physical discomfort, a growing baby pressing on the bladder meaning frequent nighttime wakeups, restless legs, heartburn, and genuine anxiety about labor and the baby all layer on top of one another.
What helps, broadly:
🔹 Sleep on your left side, especially in the second and third trimester. It improves blood flow to the baby and tends to ease back pain.
🔹 Pregnancy pillow or a pillow between the knees to take pressure off the hips and lower back.
🔹 Limit fluids in the 1–2 hours before bed to cut down on bathroom trips, but stay hydrated earlier in the day.
🔹 Keep a consistent wind-down routine. Pregnancy is exactly when circadian consistency matters most, since so many other things are already unpredictable.
🔹 Address heartburn before bed by eating a lighter dinner, eating earlier, and staying upright for a bit after eating can meaningfully help.
🔹 Name the anxiety out loud, to a partner, a journal, or a provider. Racing thoughts about labor and the baby are one of the most common and under-discussed drivers of pregnancy insomnia.
What to flag with your OB:
Restless legs that won't settle, snoring that's new or has worsened (pregnancy increases sleep apnea risk), or insomnia severe enough to affect daytime functioning. These are common but still worth mentioning.
