Reddit mentions of Nursing Mother, Working Mother - Revised: The Essential Guide to Breastfeeding Your Baby Before and After Your Return to Work

Go to LLL meetings now, while still pregnant.

Womanly Art is good. The latest edition has some new stuff in it and is a little more "friendly", so check if you have an old or new edition.

I've read a lot of BF books, and was surprised at how accessible and readable the AAP book was.

The Kellymom site is great, and so is Jack Newman's, especially for the videos, which have been mentioned.

If you ever have to take meds, LactMed and Infant Risk are essential resources - don't expect your doc to know anything (accurate) about what meds are compatible with breastfeeding!

If you plan on going back to work, read Nursing Mother, Working Mother.

I wish that I had known that it is totally normal for babies to feed frequently, including through the night. The idea that babies "should" feed every few hours and sleep through the night is very misleading. It can cause a lot of stress when your baby isn't doing these things, and can make you feel like you are doing something "wrong", when in fact it is perfectly normal.

There are some great books like Nursing Mother, Working Mother that can help explain how to keep supply up when bottle feeding. A lot of women get lucky and have the supply to spread the word on pumping but... if you run into trouble, you don't want to accidentally wean too soon because of it. The LLL book The Womanly Art of Breastfeeding also has great advice of every kind, including pumping while working.

Of course you can give toddlers milk in bottles! Or a cup. Or you can freeze it into popsicles for when their teeth are coming in or they have a sore throat. Most women I know find that if they make it to a year, they at least nurse before bedtime or whenever their toddler hurts themselves... and ESPECIALLY when they're sick. Breast milk continues to have benefits for the immune system well into early childhood. All my friends who nursed toddlers lament the day they weaned themselves, because they got sick twice as often and stayed sick twice as long! But as other moms on here have chimed in... pumping and bottle feeding isn't usually much fun. You can always choose to only nurse your toddler in private, if that makes you more comfortable. But I would wait to see how you feel about it then.

Pediatricians should not give parenting advice, is what my mom always says. They don't have the time or energy to read every single study that comes out, even though they should if they're going to give advice like that. There is no one-size-fits-all answer to this issue, so don't listen to people who claim there is. Some parents can lay their babies down, have 1 minute of crying and they're off to sleep... or maybe 5 minutes the first night, 2 the second night, and 1 the third night... good for them. But cry-it-out can also look like a parent sitting outside their baby's bedroom door, crying themselves while the baby cries for an hour, and they won't get up and go in there because their neighbor, mother, pediatrician etc told them it will work if they just stick with it. Bullshit. Do what feels right and what works for your baby.
