Here's what I've learned:
1. The first three months suck. Don't be discouraged...they're a lot more fun after that.
2. What you eat DOES affect your breastfed baby's digestion. Things like onions, chocolate, caffeine, beans, cheese.....it binds them up, causes gas, and hurts their little tummies. Some babies are even so sensitive to lactose that if the mother eats or drinks any dairy and then breastfeeds them, they have horrible bowel aches. Be mindful of what you put in your diet.
3. Babies have growth spurts frequently during the first six months of life. During these growth spurts, they are ravenous and seem to want to eat constantly. It's irritating when you are breastfeeding, because they never want off your boob. You either deal with it, or supplement with formula.
4. There's nothing wrong with pumping and feeding with a bottle. My daughter preferred breastmilk in a bottle because the "flow" was faster than the old fashioned way.
5. Breastfed babies don't always want a boob for food...it's comforting for them. All babies have a natural need to suck on something. Some people introduce a pacifier. Others just give them a boob whenever they need it.
6. In almost 10 months since my daughter was born, I have NEVER had to just lie her down and let her "cry it out". And my baby is as high maintenance and fussy as they come. Personally, I think it's cruel. Infants cry because they need or want something and have no other way to tell us. Maybe they are tired and need to be rocked, or frustrated and need to be cuddled; but I don't believe they are just crying because they want to cry. And if she insists on crying for "no reason", she can do so in my loving arms...not alone in her crib feeling abandoned. If "cry it out" were the natural method, it wouldn't make you feel so awful. Don't do it.
7. Colic is a term that people have been using for centuries to describe babies that become fussy on a routine basis in their first few months of life. However, it's not a medical term. There is no "diagnoses" for colic. It isn't a disease or condition. It's the go-to answer when there's nothing else obviously wrong.
8. Reflux happens. Gas drops help. Talk to your pediatrician.
9. Nursing frequently is your baby's way of telling YOUR body to produce more milk to meet his caloric needs. Let him; otherwise he'll be even more upset when he's sucked you dry and is still hungry.
10. Breastmilk isn't as filling as formula or rice-cereal. A breastfed baby will need to be fed more often than a formula fed baby. Schedules are also hard to form when breastfeeding, so stressing over them is a waste of time.
Good luck, and hang tight. This too shall pass.
