Hi, Is the excessive sweating present only on palms, or at other sites like axilla also? Is there any itching over palms? If the sweating is too excessive, this may indicate hyperhidrosis, although this usually occur towards adolescence. This can be treated with drugs like anticholinergics. The redness and cracking is from frequent wetting and soaking. Keep the palms as dry as possible to control this. Sometimes super-added fungal infection occur (possible if there is itching) that respond well to antifungal creams. Kindly discuss with your pediatrician. You may be asked for few tests like thyroid function test. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Muhammed Aslam T. K., Pediatrician
