Within a few days DD's skin cleared up a lot. She had a decent case of acne on her cheeks and chin and it was starting to head up to her forehead. Not bothersome to her in any way but was annoying me. It started at about 2.5 weeks old but now at 4.5 weeks it's markedly better. I started the flax around 3.5 weeks. We also had a stretch of sunny days and had her out in it around the same time I started the flax oil.
It could totally be a coincidence but I thought I would share in case anyone else wanted to try it and report back.
