Sleep troubles

Baby STILL will not sleep in anything!!!!! She'll be 11 weeks tomorrow and has acid reflux and colic, however she has Zantac for the reflux.

But she won't sleep in her bassinet, rock n play, bouncer or the pack n play. She'll sleep in the swing for an hour during the day. We've tried to put her down a million times and she wakes instantly. seems like she's just NOT a back sleeper but I'm not comfortable putting her to sleep in any of them on her stomach. I've tried swaddling her and she either cries or breaks out of it.

Anyone else have trouble with where the baby sleeps??

My husband only wants to co-sleep if we buy a co-sleeper thing but they're still on their backs and we have already wasted a ton of money buying stuff that doesn't work.

Since she was born she sleeps on our chests. We take turns sleeping in the reclining spot on the couch with her on our chests and our arms on either side of her with pillows under each arm so they don't move!
