This is a great article about the benefits of breastfeeding at different age groups. I need to make one correction. If you are providing 100% of your infant’s nutrition then you have a 98% chance of not getting pregnant. You cannot count on your period letting you know when you are fertile because you can ovulate and be pregnant before you even have your first period. Definitely something to consider! https://www.breastfeeding.asn.au/bfinfo/how-long-should-i-breastfeed-my-baby
