hi R., congratulations! i can definitely help you with breastfeeding, though let me say that i am fortunate to have been able to stay home since having my first baby, so i do not have the experience of working while nursing, and i do not have the experience of being a single mom either. however, i did breastfeed my son for 18 mos and my daughter for 15 mos, and that was with a very active 2 year old at home with me, so i was very nervous about that. that said, i just want to tell you a few things... first of all, stop apologizing for stopping nursing your first baby when you did, i think for a 17 year old to do it at all is amazing, especially when you had so little support. you should pat yourself on the back and know that you gave your son the very best start. secondly, if you really want to breatfeed this baby, then you will, and thats it. you will make it work. everyone makes it sound like it is so hard, but its really not. i could never understand why people think its easier to buy, clean, store, mix, heat, sterilize everything for bottle feeding, as opposed to just picking up your shirt. its so easy. you may remember it being hard with your son, but remember that everything is hard with a newborn, no matter how you feed them, thats just the nature of a newborn, they are little need-machines. you probably have to feed more often in the very beginning, but by 6 weeks, if you stick with it, you will be fine. next, which maybe should have been first, i think that one of the most important things with nursing is to have support. dont let people push you around. i know how hard it was for me as a 35 year old to have everyone telling me to "just give him a bottle" all the time, i cant imagine dealing with that at 17. but by now you can probably deal with anything. when people try to discourage you, just smile and tell them that you are doing fine. and find at least one person who will be your cheerleader. and i tell you in all sincerity that if you cannot find that person, i will be happy to do it. you can call me, email me, whatever, i will help and support you. my nursing experience with my daughter was a piece of cake, no problems, but i had a lot of trouble getting started with my son, real misery in the beginning, it was terrible, most of which i attribute to my own insecurity when people,including the hospital, told me to just give him a bottle, it will be fine. well, i did, and it wasnt, and it took us about 2 months of all kinds of issues to get on track. meanwhile, my daughter was in the nicu for a week and i wasnt allowed to nurse her, so i just pumped and when we could take her home i put her right on the breast and everything was just fine. i know i can be long winded, im sorry, but i want to help and i want you to succeed. in terms of the logistics of going back to work, a good pump is absolutely essential. i have the medela pump in style, and it has been a lifesaver. i pump a lot, i like to have a freezer full, im just like that, plus you have freedom that way. i have gone on vacation with it, ive pumped enough to feed my kids while i was away for 2 weeks with it, its been through the ringer and never let me down. mine is older, it is big and bulky and noisy, i know they have all kinds now, talk to people and find a great one, a good double electric. you will need to pump at work, so you want one you can bring back and forth and that will be practical to use at work. get at least 3 sets of parts so you can always have a clean one handy. i also have a great hand pump, the advent isis, which i dont use much, but when i need it its great to have, ive pumped in the car with it, in restrooms, on planes, trains, etc, and its also good if you get a clog, use it in a hot shower, it works wonders. i would strictly breastfeed for the first 2 weeks or so, no bottles, and no schedules, just feed on demand and enjoy the time together, its so short and precious, sleep whenever you can, and drink a lot of water. i tried to feed my son for the first 2 days with no luck in the hospital(hence the bottles) with everyone and their mother in there pulling and poking at my boobs trying to help, until one nurse finally asked me if im drinking.... eureka!!!...anyway, you can start pumping a little at a time by then and slowly build up, but remember that your milk supply works on a supply and demand basis, the more you feed and pump, the more you will produce, which is great as long as you are getting onto or at least working towards the kind of schedule you think will last. you dont want to produce much more than you can either feed or pump out, if you become engorged it can lead to problems, which can be resolved just by pumping or feeding, so nothing to freak out about. just start slow and build up steadily. i dont know how long your workday is, you will have to see what kind of schedule you and your baby are on to get an idea of how much milk you will need, but if you give yourself time and build up your pumping gradually well before you go back, and introduce the bottle the same way, it should be ok. you should gradually build up to the same pumping/feeding schedule that you will both be on, i would say by at least a week before you go back you should be on track, but other working bfing moms can certainly help you a lot more with that. sorry this is so long, just be confident, once you are both in a groove, it will all be great. best of luck to you, and im sending you good l&d vibes too :) ~D.
