Workshop No. 3 will target the diet in the postpartum period and nutritional needs of the newborn and young child. Beyond dietary information, specific work will be done on motivation to take care of the body after pregnancy and breastfeeding, and especially the fight against the beliefs of the food needs of the newborn, typically found in obese mothers (fear of missing, hunger equated with suffering, the emotional power as substitute) This workshop will take place between the 9th and 12th week of the program and will be led by a dietician and a pediatric nurse.
