I'll try to add what everyone else said...
I think the biggest thing is making sure the girls know they can make mistakes (of all types) and not get yelled at/in trouble by you, your assistant coaches or even their parents. You'll have to tell them that, repeat it and put it into action. Just remember it is going to take time. They've been berated for 3 years, that lack of confidence isn't going to vanish after a couple practices.
Another thought... I always try using the basic philosophy of for every correction type thing try an include a positive...to use Little Angels example "Hey Jules! You need to keep that head down and watch the ball all the way into the glove, right?", you could add, "that was some great hustle to get to the ball". Ohhhh...and don't forget to cheer on and high five the little things, loudly and publicly.... girls being where they are suppose to be even though there was no play there, showing sportsmanship to the other team, being a good teammate, girls picking up equipment on their own, etc
I think that it may also be helpful to lay down ground rules and playing philosophies to both the parents and girls, I suspect that the previous coaches may have played a little loose with whatever rules they had. Does everyone play every position or everyone will play some infield and outfield, etc. Whatever it may be... state them and then follow it.. This will help get parents on board with what you are doing and they can help with restoring that confidence, because now the parents understand what you are doing and can explain to their child versus telling their child they have no idea why the coach did "whatever".
