Self soothing

My son will be 12 weeks old this coming Sunday. He used to nap so good for the first probably 5 weeks of his life. But nap times have gotten progressively worse each week since. No matter if I’m holding him or he’s in the crib/swing/snuggle me he will not nap longer than probably 10 min. I try to put him down as soon as I start seeing sleepy cues but it’s like wrestling a bear to get him to go to sleep. Once he’s finally asleep he’ll literally sleep for 5-10 min then wake up and cry and won’t go back to sleep for hours. By the end of the day, he’s so exhausted and hateful. I try my best to get him to sleep during the day but he just won’t. Does anyone have any advice at all? I’ve looked at everything online and cannot find any help. I’ve bought the takingcarababies course and it hasn’t helped. Idk what to do. I can’t get him to self soothe and even me trying to help him go back to sleep doesn’t work. He’s all of the sudden quit taking his pacifier too. Sometimes he’ll take it. But as soon as it falls out he wakes up.
