From my experience w a screaming baby, no naps, 20min sleeping cycles if being held, etc. I HAD to just put him down and take care of myself. I'm no good to him or my other child at the time, if I'm not fed at a bare minimum.
I found he would tolerate the swing on HIGH for about 15 minutes, if he could see me. It sat in my kitchen. I found he loved to be slinged, so he was worn a lot - bathroom, shower, laundry, dishes, fixing food even. But there were times where I just wanted to poop in peace... Never happened.
I could hear him screaming in my mind. If he was sleeping I could still hear him, he screamed so much I never got away from it. I dreamed him screaming, so I slept little, even when he did sleep.
I did discover later on that he was over stimulated and would scream as well, so sometimes putting him down calmed him down and picking him back up made him scream. It was backwards to me, but it worked. It was hard at first to tell if he was over stimulated or needing something else.
Sometimes there just is no other choice but to put baby down in a safe place and take care of yourself. I've not taken care of myself and found myself not any use to any one and very depressed in my PJs for days, no shower, no food, no sleep and in a very black place which I never want to return to. I'm not a proponant of CIO and would never suggest that sort of philosophy. What I am saying it is okay for the baby to cry while you take care of yourself for a moment -- you've fed, changed, checked, tried and tried and you need something to eat or drink -- please go and get that meal or drink of water, then return to baby refreshed and able to cope just a bit better. Now, if baby likes to be on your back and you are up to it, just put him on your back and fix yourself something to eat, but if he is going to cry whether or not you are holding him, then it's nothing you can "fix" and you need to most definitely take care of yourself so you can continue to take care of his needs.
As for food, try to fix a little more at a time, so you can snack throughout the day. Quinoa might be doable too for variety - Quinoa spaggetti is straight Quinoa (some are blends). Rice pasta also exist and is good. You can purchase breads made from non-gluten grains which are often times free of other stuff, the more free of, the worse it taste, but toasted it's tolerable (fruit spread or something that is "safe") makes it go down better. Enjoy Life has several cookie snacks and are free of a lot of things. EngerG breads are DFGF (most types, if not all, egg free to I believe). HFS time for "convienence".
Something else that really seems to work is Enzymes and Probiotics, the adult kind, just take the powder out, a little on your finger into babies mouth before eating. Mom takes them too.
Another thing, all of this can be too much for some moms. Not every mom is able to cope with this sort of challenge, especially without support. If you have support, call it in. Even then, it might be too much.
I'm going to share the following with caution. I fully support bfing, even through challenges, I'm here, I'm bfing, I'm dealing with challenges. Every day is a decision to continue bfing. Last night I gave my ds a bottle of dairy formula, thinking he might be getting over his intolerance -- he threw it up, all of it. So, I'm in a spot where I do not produce enough to supply his needs, I'm on DOM, I'm doing everything I can do given my limits of having a house, 3 other children and a dh. I can not keep up this pace, everything is falling apart (the kids school work, the house, the laundry, it's a lot to deal with), so I plan on moving him over to formula, slowly and be there by December. Well, as life would have it, he does not tolerate dairy forumla and the others taste so bad he isn't all that interested, although I got 3oz of Alimentum down him mid-moring after a nursing session. So, I'm nursing and nursing and nursing. However, if he were younger he would probably take to the Alimentum
***and this is what I have to say about that -- if you need to put your baby on formula to have a happy baby, then do it. I listened to my 2nd child scream for the first year plus of his life, it has traumatized him, he has behavior problems which do come from his rough start, he is not 100%. His verbal skills and find motor skills are delayed, probably due to all the pain he was in.
I have a 4th baby now who is not meeting milestones at 8 mo old (not sitting, not crawling, not doing a lot of things one might expect and he is small) b/c I was bfing him eating gluten. He lost 10% of his body weight and was miserable some of the time. If I had to do it all over again, I supposed I'd like to have known about gluten in 2002, but I didn't learn about it until 2005.
I'm not sure I would have gone the route I took had I a chance to do my children all over again. I do think I was too subborn to listen to anyone about giving formula to my 2nd child since I was unable to breastfeed my first, but 5 years later, I must saddly admit, it was not worth the pain it caused my son to torture him with every breastfeeding session, every meal, I did this to him, me and what I didn't know then, that I know now (which I can't blame myself for not knowing, I was searching). And now he pays a dear price of being delayed in key skill sets which I am firmly attaching to his rough start in life filled with pain, the psychologist affirmed that belief in his write up of all the testing we did this summer.
There are so many more formula's on the market today and some have a place. The orginal formula was developed for Mead Johnson's son who was Failure to Thrive and doctors pronouncing he would die. The orgins of formula are genuine to saving lives. Elemental Formulas have no allergens EleCare and NeoCate, my son tolerates these, but they are $35 - $40 per can, I have a script for either. They have no real taste. I add them to his food for calories. Semi-Elemental have broken down dairy protein in them Alimentum and Pregestimil and Nutramigen. Alimentum in the liquid is corn free. I received a case of liquid through my Pedi GI docs office representative. Then there are the dairy based, organic even (which I find sort of funny), including lactose free (which does not solve the protein intolerance or allergy) and finally soy based. My first baby was on soy, he was also intolerant of dairy, but they didn't have these other types out then, the lactose free came out during his first year of life and it 1)bubbled up like soap and 2) didn't ease his problem w dairy.
My own views of breast feeding and formula have changed dramatically in the last 8 months. I know there are times when formula is "needed" and not just done out of "ease" or "not knowing better". And I'm saying as a fellow mother of 2 children who were intolerant to my diet, changing the diet can be difficult and sometimes it still does not make the baby better. If anything I've said has you wondering, here is a test without loosing your milk supply. Every mom wants to do their best and have a baby who is content, I'm saying it's okay to try formula when nothing else seems to help.
1) give a feeding of a specialty formula, see how baby reacts
2) pump, so you don't loose your supply
3) repeat to ensure reactions are not from any built up proteins causing baby's reactions
4) continue to pump
5) what was the result?
It won't hurt to do this for a day, even nurse baby in the morning and at night or just at night.
Knowing how much pain my ds2 was in as a baby and that scream, I just wish I had someone tell me it was okay to try formula, he probably would have been a much happier baby and healthier today.
