You will go through a growth phase, where your gland tissues will grow as they become prepared for the production of milk. Once you give birth, your breast will enlarge again, due to the lactiferous glands which are essentially accumulated milk and milk ducts. Your breasts will continue to change as you breastfeed, depending on when you feed your baby and how quickly they reproduce their milk. Every woman is unique in this process and every woman will grow at a different pace. This is why Yootoo has developed a unique technology we call UGrowTM as your body goes through these processes, your maternity wear will adapt with you, ensuring you always find the perfect fit.
