Thinking of cold turkey weaning my 2 year old

I have tried to do gradual weaning for months and we haven't gotten any closer to being done. I'm almost 11 weeks pregnant with baby #2 and I would like to have a break between breastfeeding my daughter and this next baby. My daughter is extremely attached to breastfeeding and has only recently started to eat more food. She's still incredibly picky and I'm a little worried that I won't be able to get her to eat enough once I'm done breastfeeding but I figure it'll come with time.

I'm very nervous about it and how she'll respond but I'm planning on doing it in a few weeks. I want to give myself time to prepare emotionally because I know it's going to be hard. Wish me luck and leave any tips if you have any!

UPDATE: over the past week or so I cut down on almost all day feeds that way she was only nursing at naptime and at night. Then last night after nursing her to sleep at her normal bedtime, she kept waking up when I would try to get out of her bed. I was getting really annoyed. I was planning on being done next Monday but I figured, no time like the present. When she woke up again and wanted to nurse, I told her no more. I told her it was all gone. She was not happy, she screamed for probably 20 minutes. After that we got out of bed, I read her some books, we sat up with her dad for awhile and then went back to bed. She of course asked to nurse but I just said the same thing, that it was all gone. She cried for like 10 minutes but then laid down and cuddled with me and fell asleep. And get this, she slept from 9:45p to 4:30a!! She has never in her tiny life slept that long! She woke up asking to nurse, I said no. She cried a bit, then went back to sleep till 7! I'm sure it won't all be that easy but man was that encouraging.

Part of me is really sad that we are done but I'm just not letting myself dwell on that right now, I've got to get through the next few days and then I can think about it. Good luck to anyone else attempting to wean!
