I did not create this symbol, but found it floating around on the internet. I have made minor changes to it to improve its quality. If you designed it, or know who did, please contact me.
In the meantime, download high quality versions of the symbol here.
I have also created a high resolution versions of the below image, which you can download here.
Even though I didn’t create these images, I would appreciate if you could link back to babyfeedingsymbols.com whenever you use them!
