DESPERATE for tips and ideas!!

Our daughter is 14 WEEKS and still will NOT sleep without being held! My husband and I have been taking turns holding her for the last 3 months!!! The INSTANT we set her down on her back she's awake and crying.

We have purchased and tried the halo bassinet, pack n play, rock n play, the newborn insert for the bassinet, a mobile foe the bassinet, the swaddle up outfit, normal fleece swaddles, white noise machine, a heated rice pack and putting my shirts down for scent. We just broken down and bought the doc a tot, which came in the mail yesterday.

She has acid reflux so we've tried an incline as well and she takes Zantac which helps the reflux.

Any other IDEAS or TIPS?? We will try anything!!
