snowchickie79, please dont beat yourself up! All little girls (and boys) develop at such different rates. Im sorry to hear the poor little thing has been sick too
ok your questions and of course its only imo.....
1. Can you start with just no knickers for a few days/ weeks? Then build up to wearing them more and more. FWIW DD wore nothing on her bottom half for 4 1/2 months and then just when I thought she would be naked forever she finally got the hang of the knickers.
2. I dont know but I dont thinks so
3. DD was like that in the arly days too! Eventually you are gonna get her sitting on there when she wees and bammo shes going to think she is the most clever little thing ever
4. Ever half and hour? Maybe someone else can comment there. My DD hated being put there that often and I soon worked out if we did it that often she would not have a bar of it. Thats said you can reason with your little one so maybe that is the way to go. We moved ours to every hour then every 1.5 hours.
She will get it, hun. Try and stay relaxed and positive
