I would stop too, warm weather (holidays?) , lots of preparation. It feels like a long time since I did this with ds, he was dry at night long before we cracked potty training.
Not sure what the advice is now but in the weeks before I would make a big deal about showing you need to go to the loo - see if close family/your OH/your Mum/siblings are willing to do this too - encourage your dd to come with you. Make sure you have a stash of strong reinforcer/rewards they must be instant and on a shelf/visible but out of reach. Ds was a huge fan of wall.e when we were starting so we bought fab walle toys and had choc stars too for instant rewards plus stuff from Hawkins bazaar that were available only for potty time - the potty means prizes. I would try and get your dd to go to the loo with you and do a running commentary on what you are doing (dignity and privacy disappear when giving birth, you will get it back one day!)
I don't know much about social stories but they might work. Books about potty traing, talking about getting rid of nappies, poo going to pooland ( we tried that) . Maybe keeping a diary to see when you need to change a nappy, use it as a prompt to go to the loo when you stop using nappies, try and watch to see if they show signs of needing before going, maybe comment if you see the signs of peeing/ pooing- positive quiet remark to make them aware of the motion/physical act.
Be prepared, try to make sure you have people to support you, if your OH can get time off for a few days, to shop, keep up with other everyday stuff that will help! Don't go out for the first four days, other than the garden, keep the potty/potties close. Be relaxed and positive. The tiniest success should result in you giving your child amazing rewards to start with. If after a week/two weeks you can't keep going stop for at least a week, maybe more, then start again - it does get easier ime. It can be soul destroying, even with an nt child, so be kind to yourself!
It has been a while, but the memory of going through it is pretty strong, my ds refused to pee for 24 hours one time (with or without a nappy - I do think cold turkey is best but not always possible) and would hold a poo for days, was on different medication for 6-8 months, maybe longer - he wasn't having accidents because he just wouldn't go.
After the first four days I would try to have life as normal, so your dd gets used to being out and about for a short while - with change of clothes and being ready psychologically for an accident, try and be calm whatever happens.
Have some rewards for getting through the day for yourself too, a nice drink, some chocolate, something to look forward too.
Good luck, hope it is easier for you than it is for so many people!
