My Infant Daughter was Injured under Hospital Care

You probably do have some sort of case due to the mobility restrictions. What you need to realize is that IV infiltrations are very common and a lot of times unavoidable. The big thing is how long it took them to realize it had happened. When an IV infiltrates it's not always obvious either. However, IV's should be checked soon after they are started to make sure that it hasn't infiltrated. Usually, within a few minutes you can tell the infiltration when the skin starts to "swell" (which is caused by the fluid going into the skin not the vein), and the redness the accompanies it. It sounds like someone wasn't paying attention, which would be more of a ground to stand on in court.

I hope this helps a little.
