Tattoo design advice please?

I'm getting a tattoo soon to represent my miscarriage. I want to get an old-fashioned bird cage with the gate open and a little pink and blue bird flying out. I have this whole vision in my head but I also want it to say something and I can't quite think of the right thing. I don't want it to be an obvious miscarriage tattoo because it does stand for so many more things in my life. At first I was thinking of something simple like "Forever Flying" or "Forever Free". But I'm just not sure. I was also thinking of maybe putting a star in the birds mouth and writing something like "Putting another star in the sky". The baby's middle name would have been Sterling which reminds me of stars. So that might make it a little more personal but not too obvious. I don't want any dates or names to represent my baby because I feel like that's something I want to keep to myself or personally tell someone. What do you think of these ideas? And if you can think of anything at all that might go, feel free to suggest them. I'm kind of thinking of the whole "being set free" theme, but I'm open for anything. It would be a fairly small tattoo so I don't want a bunch of words. Thank you! :)
