My 7 week old daughter will not self settle during the day. She shows all signs she's tired but I'll put her in her bassinet and she'll just cry and cry. I'll pick her up and cuddle her, sometimes putting her in the front pack. She'll go to sleep after some rocking then as soon as I put her back in the bassinet she crys again. She sleeps fine at night, just not during the day/evening.
Self settling for a newborn is a load of codswallop! I fell for it to with my first and persisted for 2 months - to absolutely no avail, I followed those damn books to the letter and my DD wasnt having a bar of it. What I've since learnt is that its what babies do - they are so tiny and want you close, to be rocked and soothed and they sleep in 40 minute bursts, not these two hour blocks that the books will tell you.
I didnt bother with self settling after that, when my babies were newborn and up to six months I rocked them to sleep during the day. At night they'd have a feed and go off to sleep no drama. At around six months they were happy to go off to sleep by themselves.
There's nothing wrong with your baby, or you - its normal, rock them, cuddle them, do whatever you need to smile
You need to find the rythym of awake time and sleep time that works for your bub, for mine it was only ever 40 min naps during the day and they progressed to an hour and a half x 2 sleeps at around 6 months.
