Hi A.,
i had the very same problem with my daughter. she was almost completely potty trained by 18 months and then a month later, her brother was born and it all went out the window. it took her another 9 months or so to finally decide that she was ready to use the potty again. i know how frustrating it is (especially when you have TWO in diapers). Truth be told i dont really have any real tricks to give you because i just cant remember what actually worked. i do remember having lots of talks with my daughter about being a big sister and how big sisters wear "big girl panties" and all that. She will be ready when she's ready i guess, hang in there though and dont push too hard. if you sound super excited when you are talking about the potty maybe she will get excited about it too.
