Re: 1-year old & weaning
It absolutely is a job well done! But continuing on is, to my mind, a job even more well done. There are so many benefits to be had from toddler nursing. (Here's a great article about them: Extend Breastfeeding's Benefits.)
I have always had in my head that 12 months of breast feeding was a job well done, so to speak, and meant I gave my babies the best start they could have.
One thing that does become much easier is weaning. At 12 months a baby is still very much a baby, and a lot of babies are still getting most of their calories from breastmilk well into the first half of the second year. (My daughter barely ate more than a teaspoon or two of solid food until 14-15 months.) But once the baby's diet shifts to mostly solids, the nursing sessions start to drop off all by themselves, without mom needing to do a thing. (At 12 months, my daughter nursed 8-12 times per day. By 18 months, we were down to 4-5 times. At 2 years, she was down to 3. By 2.5 years, it was once a day, and at 3 years, she weaned herself with only the slightest nudge from me.)
Quite possibly not! A lot of moms notice no difference in their milk supplies during exercise and dieting. You might want to check out this terrific book: Eat Well, Lose Weight, While Breastfeeding by Eileen Behan. It's a much less drastic weight loss agenda than what you have planned, but it does tell you a lot a nursing mom should know about nursing and her own nutrition.
My weight loss plan is a bit dramatic with dropping lots of carbs and sugar and exercising like a maniac, so I would expect my milk would be impacted.
