Postpartum brain fog, forgetfulness, and mental exhaustion are incredibly common, especially during the early, sleep-deprived months. While it is easy to worry, it often stems from the immense 'invisible load' of caring for an infant. However, it is always a good idea to have your iron, B12, and thyroid levels checked, as deficiencies can exacerbate these feelings. If the fog feels unmanageable or affects your daily life, speak with a therapist or your gynecologist—they can provide support and perspective, reminding you that your experience is part of a very challenging, yet normal, transition.
