Hi girls) What do you recommend for good breastfeeding in the first months? I see on the Gv that many advise eating everything so that the baby gets vitamins and he gets used to different food, but I don't really feel like eating anything besides broths and tea (besides). Will this be a problem later or should I force myself to eat fruits and vegetables etc?
