Is anyone else's baby not sleeping

Janice

More than an hour or two during the day for naps? He will only fall asleep if I'm holding him. He used to be able to fall asleep on his own until yesterday. Then by 6pm he is so exhausted that he passes out right after finishing his 4th 6 ounce bottle. Then he doesn't wake up until 7am and is awake all day unless I rock him to sleep and hold him the entire time. He is 12 weeks old. He will be 3 months old on October 3rd.Everytime I try to put him down even after he has been sleeping for 40 minutes he will wake up shortly after and panick if he can't see me or hear my voice. He has a doctors appointment tomorrow to check for acid reflux cause he spits up everytime he eats and he screams when he spits up. He cries everytime I try to burp him. But he also acts like I'm going to take his bottle away before he is done which I have never done unless it's to burp him. He wakes up every morning in a puddle of his own spit up. I change his crib sheets and clothes multiple times a day. I have to do laundry daily because of it.
