Go

the

Full

40

➢ Your baby needs a full 40 weeks of pregnancy to grow and develop.

➢ Being done with pregnancy may seem tempting, especially the last

few weeks

➢ Induction of labor is associated with increased risks including

prematurity, cesarean surgery, hemorrhage and infection.

➢ Labor should only be induced for medical reasons—not for

convenience or scheduling concerns.

➢ Baby will let you know when he’s ready to emerge

Nobody likes to be rushed –
