Women who are expecting rarely know what to expect. For this reason, the November issue of American Baby has prepared a list of 12 things new moms might not know about life with a newborn. Among them:

¢ Say goodbye to your six-pack. No amount of exercise will bring your abs back to their former chiseled glory.

¢ Having a baby can change your relationship with your mother-in-law. She’ll either appreciate you more or barrage you with unsolicited advice.

¢ Others, even strangers, will question your parenting decisions, including how long you breastfeed and how soon you go back to work.
