Hello everyone, I can't figure out why my two-month-old baby has cold hands and feet, even though they're slightly damp but not wet! Why? When he wakes up, warm, warm), we change his diaper, wash him, play a little bit and everything is fine... but his hands and feet are cold, even though they're slightly damp but not wet! Should I be worried ?
