I would highly recommend reading Mothering Your Nursing Toddler by Norma J. Bumgarnerg when your baby gets a bit older. What you think at 5 months of nursing can completely change by 1 year, 18 months and on into toddlerhood. Many Mothers who think they will not be nursing when their child is 3 or 4 are pleasantly surprsied that they are when the time come. The book gives many differing opinions and is an easy read.
Happy nursing. Enjoy!!
