Sleep

Ok please tell me I am not the only one who’s baby just DOES NOT SLEEP. 3 months old, never slept well and progressively sleeping worse and less as time goes on. I have tried everything. You name it, I’ve done it. Bum patting, rocking, baby wearing, dark room, sound machine/white noise, swaddling (which we’ve had to stop for about a month as my son can roll over), sleep sack. I could go on and on with what I’ve tried. I’ve even had to cut things out of my diet (dairy, spicy foods, gassy foods, nuts). He used to sleep in his car seat but doesn’t anymore. He used to sleep in his stroller if we went out and only does maybe half the time now. Also he will NOT sleep in his crib at night only for naps. I’ve tried and he wont fall asleep or he’s up every half hour. So we have to cosleep in my bed but I need to stay completely still or he wakes instantly and won’t go back down unless I feed him (and then wakes again as soon as I stop feeding him and it turns into an endless cycle) he sleeps maybe 2-3 hour stretches at night. Sometimes 4 if I’m lucky. Please don’t tell me to watch for sleep cues because I DO. I’ve tried putting him down as soon as he shows the signs, he has the HARDEST TIME falling asleep. Our routine used to be eat/play/sleep(or attempt sleep) but now he’s miserable with play time and starts showing sleep cues right after being burped. Then because he’s only been up 30-45 minutes he has a bunch of false starts and then maybe has only a solid 20-40 minute nap IF IM LUCKY. Otherwise he just ends up staying awake and then he will be miserable because he’s so tired. I’ve tried pushing his wake windows to be longer and he will scream and cry if he’s awake longer than an hour. And he isn’t content with anything I try to do to get him to calm down (swing used to work but he’s starting to hate that too) I also still keep the rest of our routines the same: put him into his sleep sack and then sing very softly for 5 minutes while rocking him for 10. He falls asleep but always wakes up a minute before I put him down so I end up having to keep rocking him and never end up being able to transfer him or I transfer him to his crib successfully and he wakes up 5 minutes later and won’t go back to sleep. I am at such a loss? What do I do? I’ve posted in another mom group and was mom shamed lol saying I’m not doing enough and that it’s my fault my baby is sleep deprived. I promise I have tried everything he just will not sleep!!!
