Okay, first of all take a deep breathand calm down. Even if you and the baby can't get the breastfeeding dance down, it won't kill either one of you. You can suppliment, pump and feed, or bottlefeed. Second, the symptoms you had with your first child when your milk came in - engorgement, soreness, maybe a clogged duct before you dried up - you will get more if you breastfeed, for a while, until you and Baby learn the dance. A cold compress will help with all of these, and pumping a little bit before you feed will help your baby latch on better by stimulating the nipple to pop out - which will help you two learn the right method faster and easier - as well as reducing engorgement. You may also get chapped skin on your nipples - just like anywhere else that is in constant contact with saliva and then dry air. You can wash and then apply lotion - nontoxic of course - right after you finish feeding to help with this. Just be sure to wash it off before you feed again. I also found that using lip balm - like Blistex, Carmex, or Chapstick - has much the same effect on your nipples as on your lips. And it's okay if the baby gets a little bit during feeding.Take turns which breast you feed Baby from first. They tend to suck more on the one they drink from first and your breast function on supply-and-demand, so if you always feed from one side first, it will cause extreme engorgement in the one and insufficient milk in the other. The more is demanded, the more is supplied. If one nipple is sorer than the other and the baby is very hungry, feed on the good side first so that Baby's urgency won't irritate the chapped skin or clogged duct more. If engorgement is worse in one nipple, feed there first but switch sooner. The more demand is put on each breast for milk, the more it produces. If you switch sooner from the one that produces the most, it evens out the demand. The engorged one will stop getting as full, making it feel a lot better and balancing things out.Above all, have patience and ask for help if you need it. Hospitals usually have lactation counselors that can help you start and can help with any issues you may have later.
