Thanks for the replies. Im not replying individually but I'll cover some things that have came up a few times.
At midnight and 3am he will feed to sleep (I'm bottle feeding) or the feed will make him drowsy that I can cuddle/rock him to sleep. And I use white noise and keep it on once I put him down for a bit.
During the day no amount of feeding, dummy, cuddling, rocking, shushing, white noise works. He hates being swaddled and cries, screams and wriggles till he manages to get his arms free. I swaddle him with arms free or use a sleeping bag.
Doesn't sleep in the pram anymore or if he does it's just dozing on and off and he wakes as soon as it stops moving. Walk for around an hour with the dog so it's not like it's just a quick walk and he isn't getting a chance to fall asleep properly. Doesn't sleep in the car either, just seems to look about. The very occasional time he falls asleep he wakes when it stops where as when he was only a few weeks I could transfer him into moses basket.
I've gave up on the idea I'd manage any housework unless DH is off and we share it. Even just getting food, a bath, ready to go out is hard work on my own. Need to put him in a vibrating bouncy chair and move him round my house with me so he can watch.
I'm not prepared to do controlled crying.
I have a sling/carrier which I use to go out walking when the weather is okay (in Scotland so rarely 😂) so think I'll need to use that in the house. I was reluctant to do it because I thought I might be making a rod for my own back and he would expect to be attached to me for alot of the day. Seems like the done thing tho from reading the replies.
To the people who said their baby didn't need much sleep my parents said it's karma because I only slept 5 hours out of 24. So maybe he gets it from me. Thankfully parents are sympathetic having gone through it and help out when they can.
Annoyingly the one time he sleeps a week is when the health visitor comes to weigh him. Im sure she thinks im making it up lol
