Hi C.
I'm just at the end of weaning my two year old. I, like you enjoyed the special time nursing gave us and was reluctant to give it up. My son is developmental delayed so I wanted to do it with as little stress to him as possible. Here's what I did, some suggestions might work for you.
Skip the bottle. If she likes cups use them. There’s no reason to get her comfortable with a bottle only to have to take it away in a few months.
Remove one feeding at a time until the only ones left are the ones before nap and bed time.
Stop wearing a nursing bra and try outfits like jumpers, the less you smell of milk and are dressed to allow your daughter to get into your shirt the easier it will be to skip that feeding. Expect her to fuss, but give her a snack and try to distract with another fun activity like going outside at those times.
If possible, have someone else get her when she cries at night so she will have practice being soothed without nursing.
Put nursing at the beginning of bed time prep so there are activities such as reading that immediately proceed going into her crib.
Once you are only nursing at bed and naps try reducing the amount of time you let her nurse. My son usually nursed 15 minutes so I started breaking his latch at 15 always. Once this didn't elicit crying I reduced it to 14 minutes. I was able to drop about a minute a week.
Find another physically close thing you can to right after nursing so she is still getting a lot of physical contact such as putting your check on her check when she drinks her milk, or gently squeezing her between a small pillow and your body. (I know that sounds weird, but my son's occupation therapist suggested it and my son loves it, your daughter may as well.)
If possible go out one night a week over bed time so your daughter will get practice going to sleep without nursing without the frustration of having Mommy right there and refusing to nurse.
Last thing on weaning, goat milk is easier for babies to digest that cow. Also organic milk may help relieve some of your anxiety about what she is drinking. Having special milk just for the baby makes it psychologically easier than giving her the same thing you pour on your cereal.
On sleeping, my son had a very hard time with sleeping in his crib. I eventually had to lean over the crib so I could have my chest on his and my arms around him to get him to fall asleep out of my arms. I slowly moved myself farther and farther away over a few weeks till he could fall asleep without me.
Best of luck
