Why isn't it an ideal time to TT? I think anytime that your child is willing & able is a great time
Maybe if you took her out to choose her own special knickers to wear, she might be more careful about not getting them wet. I found that worked well with all 3 of my girls. Once they had their Hi5 or Barbie knickers they got most upset if they got wee on them & they soon learnt to make sure they got to the toilet in time
Sounds like Becky's well on her way now & will be TT'ed before you know it
