You are doing really well for a 2 1/2 year old. My sons were potty trained when they were 3 1/2. It happened fast with my youngest but took a bit longer with my eldest. Sticker charts worked. Getting angry doesn't work. It just pushes them deeper into themselves and they end up berating themselves because of it. When it is time, he will do it himself. He is still very young.
