Summarize the following:
Try to keep your caffeine intake under 200 mg per day. This equates one mug (5 oz) of filter coffee, two mugs (10 oz) of instant coffee, or two mugs (10 oz) of tea. Excess caffeine should not hurt your baby but could cause sleeplessness.  Non-caffeinated herbal teas like peppermint, camomile, or fennel can be delicious alternatives. You should not drink these too often, though.  Remember that caffeine is also present in other food and drink, like sodas and chocolate. Although you now can enjoy a drink now and then, try to drink alcohol only once or twice weekly. Generally, aim for no more than one glass (5 oz.) of wine, one 12 ounce beer, or one shot of liquor per drinking session. More than this amount can harm your child. Your baby ingests alcohol through your breast milk so it is best to feed your baby before drinking rather than directly afterwards. Newborn babies also need feeding more frequently so it could be best to abstain from alcohol for the first six weeks postpartum. Although it is okay to eat a candy bar or a bag of potato chips every now and then, keep those foods for special treats. Your body needs to heal and healthy foods can help make that happen. Similarly, your baby benefits from the food you eat. Strive to make healthy choices accordingly. Although you should limit junk food, you should not limit all foods with fats. Your body needs some fats. Eat dairy products, almonds, or salmon for sources of healthy fats.

Summary:
Limit caffeine intake. Limit alcohol consumption. Eat junk food sparingly.
