Chances are, your doctor has probably already recommended that you sleep on your left side during pregnancy. It might be difficult in the beginning, but the more you acclimate yourself to it, the easier it will get. Your body might even naturally want to side sleep, especially during the third trimester, as the pressure and weight makes it difficult to sleep in other positions. If you’re worried about changing to a back sleeping position in the middle of the night, you can attach a tennis ball on your back to avoid staying in the position for too long. Getting enough sleep during pregnancy can be a challenge, especially with the changes in your hormones and weight, but it’s not impossible. Just make sure to get on a good bedtime routine and make yourself as comfortable as possible. This might mean spending money on a pregnancy pillow and even a new mattress if the one you have currently doesn’t provide enough support. It might be expensive, but you’ll want to get all the sleep you can get before the baby is born.
