Days and nights mixed up

Jenn

I have a 3 week old beautiful baby boy. I’m aware he shouldn’t be sleeping through the night yet. I’m a ftm but not completely clueless. He will eat and sleep/nap easily through out the day but at night he eats and is wide awake eyes open looking around. Takes forever to get back to sleep and then it’s time to eat again. I think his days and nights are mixed up. Only way to get him to sleep is to cosleep which I did not want to do. It started by accident. We’d fall asleep in the recliner or bed while breastfeeding a couple times a few days ago now he won’t sleep at night unless he’s on me. It’s hard to argue with a newborn and I’m so tired I cave now. He won’t sleep on my husbands chest but for a few minutes. We tried thinking I could at least get a few hours of sleep. I’m so paranoid of rolling over on him I don’t sleep great with him on me at night. During the day he prefers to nap/sleep in his swing. Any advice ladies?
