NICU baby and the owlet sock after getting home.

So my youngest was born @ 38 weeks but is having complications. Tears in his lungs and oxygen level issues. I'm a very anxious person to begin with and I was thinking the owlet sock might help with having a lil better peace of mind. Did you use one with your NICU baby and if so did you find it helpful? It looks like he will be home after we get taxes back so the price doesn't matter honestly. If you didn't like the owlet or used a different product that you would suggest please suggest away. Thanks in advance.

(Pic is to get attention and also it's one of the few I have from before he went to NICU and I love sharing it)
