The American Pregnancy Association advises pregnant women to sleep on their sides. They even have a handy acronym: SOS (sleep on side).

Different maternity pillows offer differing levels of support and a number of uses during and after pregnancy. These are some of the best pregnancy pillows to help her get comfortable.
