408 24 286,276M 0.000 Postpartum Doula Nurture Session Gift Voucher (Central Scotland) <p><b>POSTPARTUM DOULA NURTURE SESSION - GIFT VOUCHER (Edinburgh)</b></p> <p>Jenny's postpartum nurture bundles are ideal for mothers in the days, weeks and in some cases years following on from birth. Jenny also tends to women who have lost a pregnancy at any stage, or a baby. No matter the outcome of a pregnancy, women should always receive postpartum care for their physical, emotional and spiritual wellbeing.</p> <p>Postpartum care is often something that families do not prepare for, however this can be the foundation to THRIVING family life, and a deep bond between mother and baby. It can also be the foundation to a woman’s health in the decades following on from birth. We can view it as an opportunity to really replenish the nutrient stores that we lose from giving birth, tending to our pelvic, hormonal and mental health, meaning a more easeful transition into our menopausal years.</p> <p>A Postpartum Doula tends to the health and wellbeing of the mother. Saying that, the mother and baby are considered a unit in the months following on from birth, and so tending to the mother directly has an impact on the health and wellbeing of baby. This if often referred to as the mother-baby dyad.</p> <p><br></p> N N 0.00 N 10 a:5:{s:16:"min_items_in_box";i:0;s:16:"max_items_in_box";i:0;s:10:"box_length";i:0;s:9:"box_width";i:0;s:10:"box_height";i:0;} A N 1766492931 Yoga Links
