METHODOLOGY PHASE 1 INTERVENTION DESIGN The intervention will be made with information derived from a focus group (FG). The main objective is to identify the barriers of a mother with obesity for breastfeeding (discomfort, delay in producing the milk copiously, flat nipple, among others) and to explore the ideas to overcome them. For this purpose, an FG will derive the elements to design a communication component according to real experiences to aim the problems for breastfeeding of obese women. The communication theory that will be used is Communication in Health as a strategy for structuring the activities. Investigators will develop a guide to lead the FG discussion that allows the investigators to identify the factors that influence the performance of breastfeeding in obese pregnant women. The main characteristic of women participating in the FG is pregnant women with obesity, the distinction between primiparous and not primiparous women and those who have breastfed before at least for 6 months.
