Been there, done that. DD wasn't toilet trained until she was about 4 months off turning 3. Ironically, she was the opposite, as soon as DS came home, she 'got it'. I wonder if it was her way of getting some positive attention when so much of our time was focused on DS, but for whatever reason, she just did it.

This was our third attempt though. We tried twice before but she just wasn't ready, so Im a big believer in the old 'they'll do it when they're ready' - which is not always necessarily when we want them to!

Try not to stress about it, depsite what people say, there are lots and LOTS of 3 year olds that aren't toilet trained!

Just keep doing what you're doing if you want to persist, but there's nothing wrong with taking a break and trying again later.
