you are NOT a failure! you are clearly a very good mom who is having a hard time due to circumstances that are not your fault! please see a good craniosacral therapist or cranial osteopath who has experience with babies. if your baby isn't latching well, a gentle manipulation to help align her cranial bones a little better could do wonders for her ability to latch and suck. lactation consultants, although they know a lot about many things, don't know how to correct for cranial restrictions that can interfere with a baby's ability to latch and suck. although a c-section may seem to be easier on a baby's cranium than a vaginal birth, it isn't necessarily - there could be restrictions from the sudden decrease in pressure and/or from the baby's position in utero. there could also be trauma from intubation or suctioning after birth, which could make your baby averse to having anything in her mouth. if this the case, you could try offering your pinky finger or your breast for her to suck on, and if she pulls away and cries, empathize with her, saying something like, yes that was awful having that tube down your throat, i'm so sorry that happened - that's over now and this is different, and you can take your time, i'm here for you (whatever words come to you - babies really do understand these things). you could also try expressing a little milk from your breast into her mouth even if she isn't latching, so that she begins to learn to associate the breast with yummy sweet milk. does she suck on your finger well? you can try that, and use your finger to gently encourage her to get a better suck (you could also put a little breastmilk on her finger for the taste). i agree that you should also check for tongue tie if you haven't - it can be resolved by a quick and easy snip or by gentle methods of pulling on the tongue to stretch the frenulum. finger feeding her your milk through a tube attached to your finger might be better than bottle feeding as a temporary transition to breastfeeding, since the sucking needed with a finger is closer to breastfeeding than a bottle would be (therefore less likelihood of nipple confusion). as far as protecting your milk supply while your baby learns to nurse, do you have a really good pump? if not, it would be well worth the extra expense of renting a really good one, to make sure you don't lose your milk supply. and it's true that with c-sections, milk can take longer to come in, since you and your baby didn't have the benefit of all the hormones, and both of you have been traumatized at least physically if not emotionally. it sounds like your milk may not have "come in" yet, or it may be that the pump isn't doing as good of a job as a baby would. you could even, if you have any friends who are breastfeeding, borrow their baby to nurse on you (obviously it should be someone you know and trust that they don't have any terrible diseases). as far as the volume of milk, a general guideline is to multiply the baby's birth weight by 2.5 to get the # of ounces they should have in 24 hours, and then divide that by 8 feedings if you're pumping or nursing every 3 hours. for example, an 8-pound baby would need 20 ounces in 24 hours or 2.5 ounces every 3 hours; or a 6-pound baby would need 15 oz in 24 h or 1 & 7/8 ounces every 3 hours (or if it's every 2 hours it would obviously be less per feeding). it's good that you have a history of successful breastfeeding and an abundant milk supply, so you will probably do just fine once you get going. having 3 kids can certainly be a handful, especially after major surgery, which could be impacting your ability to relax and let the milk flow. it would be wonderful (and maybe even essential in order to get off to a good start with your baby) for you to have lots of support, people to take care of everything else but the baby (cooking, cleaning, laundry, playing with the other kids etc), so that you and baby can stay in bed all day, skin to skin, and allow yourselves the time to really fall in love (also catch up on sleep, letting yourself sleep whenever baby does). of course your other children will need some attention from you, but if other people can take them on some special outings, that will allow you more time with your baby. sorry this is so long - i've just seen so many mamas have problems that could have been prevented with the right kind of help and support early on. if you do need to supplement for a little while, it would of course be much better to give her donor breastmilk rather than formula, such as from a friend or from a milk bank. so - after saying all this, it does sound like, aside from your milk supply, your baby may actually have some specific issues with latching and sucking, which could be helped by craniosacral therapy or cranial osteopathy, and/or clipping or stretching a tight frenulum, and/or releasing any trauma from suctioning or intubation etc. so, in order of importance - 1) your baby needs to eat! if not directly from your breast, then as close to breastfeeding as possible, so that she can more easily transition to breastfeeding. 2) you need to protect and increase your milk supply, by pumping or nursing another baby, if your baby won't latch yet. 3) baby needs to be checked for and helped with anything that keeps her from latching and sucking well (cranial restrictions, tongue-tie, trauma). i really appreciate you reaching out for help, and i'm glad you've tried several lactation consultants. maybe the next one will be the one who will really help - or maybe your milk will come in and your baby will just suddenly get the hang of it! in any case, hang in there, remember you are a wonderful mother, and keep us posted!
