with my daughters I breastfed until they grew teeth in fear of me getting bit.. yeah I know. well with my first I couldn't produce much the first month, I was disappointed. she was still hungry so I went to formula. now with this, I want to fully breastfeed for a year exclusively! no rice cereal or oatmeal. nothing but the fruit and veggie Gerber. i don't know if I want to use a bottle but sippy cups.. to avoid that weaning which was really difficult for me with the first two to take away. what you guys think? I know I'm the end it's my decision and all. what have you done and stuck to? I heard there's a breastfeeding app called feed baby, who had used it?
