I know its hard. But 6 weeks is still very young.
I don't want to scare you, but in reality it may be 2-3 weeks before you see a change, especially because CC/CIO was used in the past. But please keep trying. It really will get better.
Don't feel guilty, when we know better we do better. No one here believes in CC/CIO but they also wont judge you or critisize you. We're all here for you. If you feel guilty he will sence that.
Did you read about the 5 S's in the last post I sent for you? (in a previous question of yours)
Pat/shush is hard work, good for you keeping with it.
Have you checked out the EASY bored at all? I highly suspect some changes in routine will also help with fussyness. If your LO is overtired it will take a lot longer to settle him. AS hard as it is to hear him cry, some crying is normal, but its easier for him to do it in your arms, (OK so maybe not for you
) but really it'll build a strong bond and he will learn to sooth himself rather then close himself off.
Don't use babywise, thats too rigid. Babies don't go by the clock, instead follow his cues, let him lead the way. Sounds crazy, but it really helps. He knows when he is tired, hungry, bored, if you listen you can learn to understand. Takes a lot of work and time, but when you learn it you feel so much better.
You need a routine NOT a schedual. This way there is more flexability.
This will eventually settle into a solid routine, but really at 6 weeks, let loose and just watch him. Take a few days, stop and step back. Write everything down, thats what we did with DD.
I took 3 days and wrote everything, eating sleeping, peeing, pooing, everything, and you know what, a pattern developed that made making and EASY routine a lot easier. It followed her natural order and thus was easier on us both. Its about flexablity and in the end respect. You cannot expect him to fall into a routine right away, more then likely a solid routine wont really develope untill closer to 8-10 weeks. It can take 2-3 weeks on solid work to get a good base for a routine, once you have it though your good to go, only minor tweeking to meet his development and age.
Until then relax (hard I know) but really its true. If your stressed he'll stress, if your calm, he'll calm.
Also do the baby type test. Find out what type your baby is. Do that now and you can better understand your LO, a spirited baby needs different treatment then an Angel baby. Remember sleep signs are so suttle that you really need to watch. My DD is Spirited and for the longest time if I saw her Yawn I knew it was to late
it was all bad, then I finally noticed her eye's started to go red and swell, ever so lightly, and BINGO!! I found a sleep cue I could finally catch
but that wasn't untill about 8 weeks I believe, maybe a bit longer.
Do it again in a month or so and you may find your LO is actually a different type, and just needed some help to get there.
Take a big step back and breath, you need to lower your expectations just a little. We've all been there, especially when its the first time, I know I was. But its true, once I lowered my expectations, she surpassed them.
You cannot expect a 6 week old to go 1.5-3 hours with no sleep (I did
and it made me go mental) you cannot expect a 6 week old to only eat every 3 hours (some will, but its also an age for a growth spurt, most need feeds every 2 hours, especially BF babies) You cannot expect a 6 week old to self sooth (they just can't do it) and you cannot expect a 6 week old to "sleep through the night (anyone says theirs does is more then likly lieing, VERY few do.)
hth
P.S. your doing the right thing, your a great mom. Just keep saying that
its true!!!
