Hi, Emzy~
What a sad situation.
Here is something that most people don't know.
When babies go through the birthing process, they can sometimes experience trauma and injury that goes undetected. This can affect sleep, mood, and emotions. For this reason, it is really helpful to have babies checked out by a chiropractor because they know about this and know what to look for.
A simple little adjustment can sometimes make a world of difference.
It is certainly worth a try.
Have a very happy and peaceful New Year.
