Can I Become Pregnant While Breastfeeding?
Yes, you can become pregnant even if you have not had your menstrual period since your baby was born. If you are breastfeeding it may take several months for your menstrual periods to start again. You may become pregnant before your first period if you are not using birth control.
Birth control methods that use hormones, such as 'the pill', 'the patch' or Depo-Provera may decrease your milk supply. Condoms, spermicidal jelly and diaphragms will not affect breastfeeding.

What Should I Eat and Drink?
Healthy eating is good for your body, especially when you are breastfeeding. While you are breastfeeding you may feel more hungry and thirsty.
Eating well with Canada's Food Guide gives you advice on how to choose foods.
If you do not have a copy, please ask your doctor or midwife, a dietitian or visit Health Canada's website: www.hc-sc.gc.ca (click on Canada's Food Guide)
Every day, enjoy a variety of foods from each of the 4 food groups:
Healthy foods to choose more often are:
Eating Well with Canada's Food Guide gives a range of servings for each food group. Follow the guidelines for breastfeeding mothers.
You do not need to increase the calcium in your diet while breastfeeding.
Caffeine is found in drinks such as coffee, iced and hot tea and cola. Foods like chocolate that are made from cocoa contain caffeine too. Caffeine is also found in some medications for colds or headaches.
Caffeine passes into breastmilk. If you drink a moderate amount of caffeine there should be no effect on a healthy full-term baby. A moderate amount is no more than 3 cups (750 ml or 24 ounces) a day of drinks that contain caffeine. Please note, caffeine may have a different effect on a preterm or sick baby.
Alcohol and Drugs
Alcohol passes into breastmilk, so it is best not to drink any alcohol, such as wine, beer or liquor while you are breastfeeding.
If you choose to drink alcohol while you are breastfeeding, it is best to limit yourself to small amounts, drink with food, and when your baby is not likely to breastfeed for a few hours.
For example, if a mother who weighs 150 pounds has 2 alcoholic drinks, it will take 4½ hours before her breastmilk is clear of alcohol. If her baby is ready to feed before then, it would be best to feed him breastmilk that was expressed earlier, when the mother’s milk was clear of alcohol.
Recreational or street drugs such as marijuana, are not recommended during breastfeeding.

Food That Affects Your Baby
If you think your baby seems to get gas or become irritable from certain foods you have eaten, stop eating them for a few days. Then, try them again in small amounts to see if your baby is still affected.
