<s>[INST] My son is 6 weeks old and he is breastfed only; the inner part of his lower lip has developed dark patch-like spots. His daily routine of sleep, feeding,nappy changes and the ocassional crying has not changed; everything seems normal. Should I be worried about the changes on his lips? [/INST] Hi....as his daily activities are normal, you need not worry. But one most important suggestion - Skin conditions are best diagnosed only after seeing directly. I suggest you to upload photographs of the same on this website, so that I can guide you scientifically. Hope my answer was helpful for you. I am happy to help any time. Further clarifications and consultations on Chat Doctor are welcome. If you do not have any clarifications, you can close the discussion and rate the answer. Wish your kid good health. </s>
