Hi J.,
I have been where you are and I feel for you. If it is any consolation, you are probably in the worst of it right now. In about a month, things should begin to get better, both from an exhaustion and breastfeeding standpoint. That said, it will probably be several months before you feel truly well rested again. What to do in the interim?
Based on my own experience, I have a few suggestions. First off, if you are not still in touch with a breastfeeding consultant, you may want to reach out to one again. She might be able to help you address the specific issues you are dealing with now. Your pediatrician or the La Leche League may be able to point you in the right direction. There is also a very good book on breastfeeding called The Nursing Mother's Companion by Kathleen Huggins.
In addition, you may want to consult your pediatrician about the possibility that your daughter has acid reflux. The back arching is a classic symptom of this disorder, although not a definitive one. If your daughter has reflux, she may be in pain when she eats, which could cause her to take less milk at each feeding, making her hungry more often. There are several reflux medications that have been used safely for years in infants. If your doctor suspects your daughter has this disorder and the first medication prescribed does not seem to work, don't be shy about asking to try a different one.
While breastfeeding offers clear advantages to babies over formula, there is something to be said for a happy and well rested mom as well. And one of the advantages of formula is that it keeps babies satisfied for a longer period, which means if you use it for one of your night feedings, you may actually be able to get a good chunk of sleep in. That said, you should be aware that the introduction of formula usually spells the end of breastfeeding over time.
The challenges of pregnancy, delivery, and early motherhood are profound, and we embrace them with a committed heart and the best of intentions. If on occasion we do not live up to the expectations we have set for ourselves, than so be it. Breastfeeding is clearly best for a baby, but no matter what the breast feeding bullies out there say, your child can be fed formula from day 1 and grow to be a happy, healthy, well-adjusted child.
In my case, my son (who is now 19 months old) was never satisfied with my milk supply, had wicked colic (crying beginning at 11 am and lasting well into the evening, no naps), and acid reflux. I introduced a small amount of formula in the evening to satisfy his insatiable hunger and allow me a few hours of uninterrupted of sleep. Over a period of several months, the amount of breast milk I produced slowly decreased and the amount of formula he took slowly increased and at 5 months I was producing so little milk it seemed pointless to continue with the breastfeeding. I was disappointed in myself, but 5 months of breastfeeding was far better than none. I am currently 7 months pregnant with my second son, so these issues are top of mind at the moment as I consider how to avoid the pitfalls I met with the first go round.
In your situation I suspect that if you can keep at the breastfeeding with a little help for the next month everything will fall into place. But if you opt to supplement with formula or stop breast feeding entirely, the world will not end, you will still be the same caring and devoted mother you have been, and your daughter will continue to thrive. Be kind to yourself and have confidence that whatever decision you make is the one that is best for you and your child.
I wish you all the best. It will get easier and you will feel better in time. But is sure is a tough road when you're on it.
