All I can do is share my experience. I, like the other moms, feel that it is hard to "spoil" a newborn. I was a very stressed out newborn mom, the first 2 times. I have 4 now, from 20-5 yrs old. First 2 are girls, second 2 are boys. I think with the girls I was inexperienced and afraid. They cried alot and I held them alot. I was not very creative with keeping them occupied either. My babies were exhausted and so was I. They continued to sleep less and less and fuss for me to hold them more and more. Both of them, at around four months, my doctor told me to put them in their cribs for naps and bedtime and let them fuss. Go in after 2 min, reassure them (without picking them up or turning on lights) and walk back out. Then go 4 min, go back in and repeat for as long as it takes, stretching out your time. He assured me this would go on no more than 3 days. He was right on every count.
Basically what starts for one reason, continues for another. You are giving your newborn security that they need and you only get this time for a few months. They do however quickly get use to it and no one is getting good sleep. They were eating more than they need which was causing upset stomach...for mine sometimes they would fuss even when I was holding them, just not as much. I thought maybe they were still hungry(nursing you can't really gauge).
The goal, in time, is that they know that they can be seperate from mommy and be ok because mommy will return. But not just yet.
Sometimes it becomes a habit that you need to break. My doctor told me by 5 mo they eat enough during the day that they should not be getting up for night feedings. If they sleep more than 8 hrs they may get up for one. (Of course this was my babies and they were big babies that nursed plenty throughout the day) This is true for formula fed babies as well, because formula digests more slowly.
As for now. You can buy therapedic pacifiers online that look like a pinky finger, the whole pacifier is silicone (I think it is silicone) anyway much more like human skin and easier for baby to keep ahold. When my newborns would fuss and they had their needs met and still they cried I would turn my hand, palm up, and let them suck on my pinky finger (can't have nails) right to sleep every time(this provided the sucking but they were not getting unnecessary food to try to digest). (Some people think that is weird, and that is ok)...just some ideas. You can google it...not sure what you will get but I know some famous moms have done it. You can also try Le Leche League website, not sure what you will get there either. My sister is a massage therapist, and she worked miracles. I would also encourage infant massage classes in your area. They will teach you how to calm your baby when fussy, massage when they have stomach upset and so many other great things. Try wrapping your baby up tight like they did in the hospital. (Mine would fuss at first, but when I put them down and turned on the sound machine they were out. I also used a wedge under their crib to prop them up a bit. There are items that you strap to their cribs now that are light shows with music operated by batteries so they won't shut off. Remember whatever you try they will not go off to college doing. So what, if you get a quiet shower because they fall asleep to the vacuum. Yes that is the only way one of mine would let me get a shower in when she was a newborn...then I was good through the blow-drying as well. She also took a nap while I prepared dinner to the oven vent. And it had nothing to do with noisy siblings etc. that is just what she required for the first few months. You can always use a Snuggly to tote your baby around with you. At about 14 wks it was gone. She was sleeping in her crib just like the doctor said she would. She was a bit more stubborn than my first. She actually had me up 2 nights in a row back and forth every few min. And...every time she got sick we had to start the process over. We really are training them. That is our job, to give them structure that they can count on and feel safe and secure. Running to their every demand and always on a roller coaster is not security...and the sooner you train them the safer they will feel knowing what to expect from their parents(or any caregiver they may have)...who absolutely need to be on the same page with how you respond to your childs needs. Still I think newborns are an exception. You try different things to get some free time but it still may not work tomorrow. It is just 3 mo of experimentation for some. And no one could ever convince me there is any value in letting a newborn cry.
Most importantly, you need to feel confident in being that babies mommy, and you need to get your rest. If that means stealing naps when they do, because they will take a nice long nap with you beside them, then do it. Use the support system around you to get some down time. If you don't have one create one. Remember this is only temporary. Whatever you choose to do, make sure it is consistent so that they get use to a routine. My 2 oldest, I gave nice warm baths and snuggled in the rocker to nurse just before bed every night...unfortunately for me this is after I had exhausted my other options...that appeared to be what they wanted. I would hold them and try to put them down, when they fussed I would pick them up and try again. Hold them until they fell asleep, put them down, until they fussed. My doctor said to busy them, relax them, lay them down awake and go. For me that was bath, snuggle and nurse with lights low, and to bed. I did that from the beginning with the boys with some alterations. I should say, however, that I slept with my babies at bedtime (ease of nursing) and they slept in cribs for naps. This was true until they were 3-5 mo old, then to their cribs they went.
Finally, all newborns are different. My last 2 were angel newborns. Loved to be held, loved their beds. Usually only fussed when they needed something. Looking back, it may have been me in training, I was a pro by then...and if you are a first time mom don't be afraid to experiment...they won't break, go off to college remembering how you let them fuss a few times or need cows jumping over moons on their ceilings and Mozart to sleep forever. They do, however, have an uncanny way of sensing us. Get the time and revitalization that you need, you will be doing your baby a favor.
