Hi, I m at my witsend, my baby has cold clammy sweats, she has sweat on her head, back and arms. She is now 13 months, I noticed this when she was a month old, it was mainly her hands and feet. I strip her down to her diaper and she is still sweating even when it s hot or cold. The pediatrician has said she may be having a hard time regulating her body temperature. I am really worried, she has had an EKG at 12 months and as best as it could be done, they said all looked well. What causes this excessive sweating?
