Thanks for the update! How fantastic that your crack healed. That must be a huge relief!
It's hard to say how much longer you will need to use both hands to support and position baby and breast while nursing. It depends on how fast your baby grows, and how fast she gains strength and coordination. That means a different answer for every mama-baby pair. But don't worry- you will NOT be required to use all your hands forever! I am willing to bet that by 3 months you'll be able to nurse comfortably in public, and the baby will be able to latch with little assistance.
