co-sleeping it's called?

Aurora

My baby girl won't sleep in her 129$ bassinet, won't sleep in her 1000 crib, I'm at a loss since week 3 we've been sleeping with her in bed, on my side I hold her with my arm under her legs and I sleep on my side and my face close somewhat so I know if she moves, I wake Up About 15 times to make sure her head is right and what not, she's 8 weeks old, we get sleep, I'm talking 7+ hours when she's in bed and she naps in bed since last week with me at 1 pm until 5(now 3ish)wanted to Be more awake, what can daddy and I do?! I'm going to try at 3 months and then again at 6, when can she put herself to sleep? We don't want her chewing at her hand and thats what she was doing in the bassinet, and just crying non stop, she really loves it when I pat her booty 💜 mommy's girl.. Now I only weigh 94 pounds and I sleep always on my side and she's on my pillow, I'm on it a little bit... But I can't sleep like now,, she's sleeping and am I'm doing is worrying.. I'm going to ask her doctor on what to do, but I was wondering if anyone else had this issue, will it be forever, I mean I could sleep in her bed!! Lol I'm tiny
