Hello girls, please help me! I can't take it anymore, my child is over two years old and still breastfeeding at night. We drink 150 ml every 5-7 times during the night. If I give more, he doesn't finish it, leaves some for a while. He eats all of it in the day four times. At night we also feed him and it's useless.
