Congratulations on nursing your baby. It sounds like you are a wonderful mother. Your baby is lucky to have a loving & nurturing mother like you. The best advice that was given to me was to listen to your child and meet their needs. It is actually normal for children to want to nurse past a year(look at the rest of the world who nurses well past 1-2 years). How many children have you seen with a bottle or pacifier at the age of 2-3. One prominent Doctor, Dr. William Sears(who wrote the Baby Book & other great baby books)says that needs met when our children are young will go away. But when we denied those needs and don't meet them they come back later usually in adolescent and never go away. Just remember your 15 month old is still a baby. I am nursing my 17 month old and believe it actually gets easier because soon they won't nurse as often and they are happy and more content and isn't that what we want. Besides breastmilk is the ultimate brain food and children's brain grows faster in the first 2 years than it will ever grow again in their entire life. It actually grows 70% of what it will be as an adult. Why not give them the best for the growing brain & nurture them at the same time? Believe it or not, when they are done nursing they will tell you. My daughter weaned on her own when she was ready & today she is very confident, extremely intelligent & loving.You are doing a wonderful job. Keep up the Great Work!!!
