This is the advice I was given by a lactation consultant & pediatrician:
* Nurse when the baby was happy, so that nursing would be a pleasant experience for both mom and baby.
* Never nurse your baby when he's starving, as it may become an unpleasant experience for the baby and it will stress you to boot.
* Try to feed frequently and on demand - about every 2-3 hrs was right for my son. Waiting 4 or 5 hours between feedings is Ok only if the baby is on formula exclusively or asleep (do not wake them) - breastfed babies must be fed more frequently. If you can, pump after you nurse to increase milk production
* Take Fenugreek herbal supplements (1-2 capsules per meal) to increase your milk supply, especially if your child only nurses for short periods - only if OK'd by your doctor if you have a history of diabetes. Otherwise, high protein meals and milk help. You can try fenugreek tea as well but this was less effective.
* Make sure the baby's positioned correctly. The baby's head should be halfway between your wrist and elbow, she should be facing you, and her body should be resting under the opposite breast (the baby should not be horizontal). Use a cushion or nursing pillow that can be molded (like the one from Sealy, sold for $14 at Bed, Bath & Beyond) to help support your arm and keep you from getting tired.
* Sit in a comfortable spot. I have a glider but don't use it anymore - I found a $20 backrest with armrests from Bed Bath & Beyond to be far more effective in supporting my back. I sit in bed and nurse my son.
Also, if you are using a Boppy, it is too high in some cases and holds the baby horizontally, as opposed to diagonally. A softer nursing pillow that you can adjust is better, but be careful with a young baby if she falls asleep.
On my own, I found these helped my son nurse longer:
* Bribe your baby with soft materials. I got cozy micro fleece or velour longing sets from Costco ($20 each) that my son loved to cuddle up to while nursing, and are good PJs to boot. Clothes also made a huge difference in my outlook - J Jill and Macy's Charter Club both sell great jeans and pants that are made of stretchy material that fits great and is very forgiving to the extra pounds. J Jill also has great velour tops (like velvet) that are machine washable and/or can be wiped off easily in case of spit up.
* Watch your diet - strong foods (garlic, spicy food, cabbage) can alter the taste of the milk.
* Keep your weight up. I got used to the belly fat and upper arms, thinking of it as padding for my son. I kept on 20 lbs on purpose to help with breastfeeding, by eating 2200 calories a day (chicken, cheese, PBJ sandwiches, juices, mixed green salad, Nesquick cocoa w/ whole milk and Kushi granola bars are the basis of my diet). If you add Ensure or Ensure Plus to your diet, the quality of the milk (fat content) will improve.
* Avoid tension in you -If you are worried or upset the baby will sense this.
* Watch out for too many distractions - TV, radio, people, etc. Go to a quiet, dim-lit room.
Whatever you do, don't take this personally if the baby doesn't want to nurse. There are a lot of causes for it and several things you can try. And as always, if she doesn't nurse, or doesn't nurse much, pump afterwards so it doesn't affect your supply.
