This one works like magic, but I wish there was a lavender-free option.

I know the lavender is one of the active ingredients and is great at healing skin, but I’m slightly uncomfortable with using it on an infant frequently because it is phytoestrogenic to some degree.

Happy enough to use it and heal my child, just a lavender-free formula that still worked would be ideal, is all.
