Re: Changes at 12 months?
It depends on your nursing goals. If you want to drop sessions, offering solids before nursing will help you do that. If you're comfortable letting your baby wean at his own pace, you can continue to nurse before offering solids, or just be relaxed about it and sometimes offer breast first, sometimes solids first.
As one of the PPs said, nursing a one year old is a lot like nursing a baby. There's no big change that happens on day 365. But over the course of the next year, things will change a lot even if you do nothing to try to make them change.
