Trying to potty train my DD she will be 3 next month. Getting conflicting advice some have said she needs to wear knickers to get use to them. But when I do she just wees/poos in them like they are a nappy. Having more success if she doesn't have them on. However I'm concerned this will mean when we go out she will just go back to soiling herself. Would appreciate any advice at all really finding it quite difficult. TIA
