Potty training help

My daughter will be 3 in October. We introduced her to the potty earlier this year. She is not to the point where she will tell us if she needs to go but have not had a problem getting her to sit on the toilet. That is until about 2 weeks ago. Now, every time we ask if she wants to sit on the potty the answer is no. We are also in a "no" phase for the majority of questions. So, instead of asking, I'll tell her it is time to sit on the potty. But she will refuse and go in to full tantrum mode if I push the issue.At daycare, they have more luck getting her to sit. Though there are times when refuses. At home, it has just been a constant refusal. There is a relatively new sibling in the picture but she is 7 months now. My in-laws are visiting and arrived earlier this month. The will be with us until October. But, she seems to like having her grandparents around.So, do we continue to encourage her to sit on the potty? Or just drop it completely for a period of time? Thanks for the advice! via /r/Parenting http://ift.tt/291C1v4
