Healthy eating is still important 

Your partner’s body continues to change. As her belly stretches, her breasts are getting ready for nursing, and may secrete a few drops of colostrum. This yellowish liquid is a baby’s first form of nourishment. It precedes milk and favors the growth of the baby’s intestinal microflora. It also contains antibodies that can protect them from infections [1]. 

Moderate edema is a typical part of pregnancy. Your partner’s legs may be swollen due to hormones, pregnancy weight, and changes in blood circulation [2]. To get some relief, she can put her feet up and do some light stretching several times a day. Increasing her water intake can also help [3]. 

In the final weeks of pregnancy, some women may be tempted to be less strict with their nutrition. But it is not the time to go overboard with cookies, sweets, or chips! The baby still needs a diet high in nutrients, and too many empty calories can predispose them to obesity and make the mother gain unwanted weight that can interfere with her postpartum recovery [4, 5].

Keep enjoying a healthy, varied, and nourishing diet by including lean protein, fruits, vegetables, and whole grains in every meal. Studies show that future dads can also gain weight so a balanced diet is good for you too [6].
