Sisters newborn

[AnAussieMum]

Hi all,
I am a long time reader first time poster.
My sister had her first baby 10 weeks ago at 39.
He's the most beautiful baby boy and this is my first time at being an aunty so I am super excited. I myself have 3 girls, I was pretty lucky my girls were pretty good as babies.
My poor sister is having the worst time at the moment and its been ongoing since he was about 3 days old I think.
He just seems so unhappy, he is very hard to settle.
He crys ALLOT and won't sleep. When he does sleep and she puts him down he wakes straight up.
He won't self settle AT ALL!
He just seems to want to sleep on her.
She has tried everything that we can think off and I am at the point that I feel like now its just him. There's nothing that she can do except ride it out.
Her partner works away and has 1 on 1 off roster. He's just gone back to work last week however my mums there every night to help her as he isn't getting to sleep until about 11.30-12 at night.
Shes trying to get him in routine of some sort so she said she's bathing him around 5.30 but then spends the rest of the night trying to get him to bed.
I spent the day with her today and went to the shop.
So his routine as far as I know went.
Last night bath 5.30 finally settled 12am
7am woke up and had feed.
8am back to bed and woke at 1020.
Cried on and off all day, she fed changed burped everything we could think off.
He tends to spend 5-10 mins happy then cries until we can either settle him or he is fed again.
I left her at 210 and he was still not sleeping, just crying.
He is tired, you can see he is fighting sleep. I believe he spends so much time fighting sleep that he is then over tired. Then its been so long he is hungry and it just goes around in circles.
Its heartbreaking for her and of course for my precious nephew.
I would love to know if anyone else has some tips and has experienced any of the above issues.
Thanks in advance.
He hates the car and cries the whole time he's in it. I sat in the back with him today, tried talking to him, touching him, singing to him. The only thing that settled him was watching a random video of childs birthday and everyone singing happy birthday. Over and over and over again.
He hates the pram so she really can't even walk him as he screams after about 5-10 mins.

Have I understood correctly that he is sleeping from midnight to 7am? Although it's very late I think a 7 hour stretch sounds pretty good at that age.

Your nephew sounds like my eldest. She would only sleep close to me and slept in my bed, more or less in my armpit, until we started sleep trained her at 7 months. She went to sleep around 7:30pm but would wake up within about 20 minutes if I snuck off and left her on her own. It was a PITA, but she actually slept really quite well by about 11 months and is a fantastic sleeper now at 4.

She loathed the car- really absolutely hated it until she was about two, although if she was tired it would get her to sleep. She also hated the buggy, but was generally happy in the sling. I never got her to nap in her cot.

I thing some babies are just like this. Given my time again I would try to roll with it as much as possible, as I think I made a tiring and inevitably sleep deprived time harder than it needed to be by worrying that I was doing it wrong and trying to get her in to a more "normal"'routine.
