I have just trained my 2 yr old this is what we did. We sat her in front of the TV NAKED on a towel on her potty chair and let her watch anythong she wanted (Finding NEMO/ Lilo & Stich) gave her lots of soda-pop and every time she had a success praised her and gave her 2 M&M's. We did this for 2 days stright and she has been using the potty ever since (not at night mind you that comes later) but it has made life much easier I think since we have done it (2 weeks ago) we have had 2 accidents.
hope this helps you out it helped me out a lot when my friend told me about this plan
