Can a pillow between my legs help my insomnia?

Help my insomnia? Sleep hygiene is best approach for insomnia, however, if u feel the pillow can help u, there is no harm in using it.
Yes. Part of what keeps you up at night is the joint pain. During pregnancy your joints all are loosened from hormones. The hips can be especially effected. A pillow between the knees can help relieve the joint stress.
