My 11 mo. old daughter has been exclusively breastfed up until now. We have slowly been doing baby-led weaning with fruits and veggies, but have not given her any water. I hope to breastfeed for a long-time and have my baby wean when she is ready. I am having a hard time finding definitive information on when an exclusively breastfed baby needs to start getting sippy cups of water...and how much per day? The only information I found says that thay don't need any supplemental water until age 1, but what are the requirements for after 12 months old? Thanks in advance!
