Co sleeping with 1 week old

Before I start, please do not comment anything judgmental. I am a first time mom at 20 years old just trying to figure things out.

My son is 1 week old and since 3 days old we have been co sleeping. I was completely against this before birth, but the first few nights trying to get him to sleep in his bassinet was torture. I was up all night & it got to the point where the 2nd night, I cried the whole night trying to nurse him & keep him sleep.

With co sleeping, I notice he wakes up 2-4 times during the night & he sleeps for about 1.5-2 hours each time he wakes up.

I know that co sleeping has led to SIDS & other risks, but this is just so easy & helps so much with me getting sleep too. I am extremely careful & make sure there is a good amount of space between baby & us as well as make sure our pillows are far away from his face.

Is there any tips from anyone that has co slept with a new born? How did you get him to sleep in his bassinet?

I’m thinking maybe it’s too hard & not comfortable for him. We have tried 2 different bassinets that he has rejected.
