Our son started potty training himself at 25 months, so close to your sons age. He hadn't had juice before except maybe here and there at other people's houses like when Grandma had him or MAYBE birthday parties. (We put it off and limit it because of the harm it does to teeth.) But it worked GREAT for potty training. He'd sit on the potty with his little cup of juice. That was enough incentive for him to stay on the potty. And it didn't take long before we had opportunity to praise him for peeing on the potty (juice gave him ammunition to go). So he potty trained VERY easily and early particularly for a boy. When he would go, he's get truck candy (a piece of the monster jam fruit snacks) and when he went poopy he'd get a different piece of candy like from his Easter basket. So, I'd say go with it. I wouldn't push or anything. Just keep letting it be his idea. The Bjorn potty (9.99 at Babies R us) is EXCELLENT for boys. The guard is built into the molded piece of plastic, so it all gets into the potty and so easy to clean. Worked great for my first and is working well so far for my second (though he's just 21 months and a stubborn one, so we are at the VERY early stages with my second). He may regress with the baby or he may not and may regress with something else, but why not go with it and see. We like the once upon a potty. Honestly it didn't do much with my first because he was so self motivated, but my second LOVES to sing the potty song and watch the babies. He also tells us when he poops or pees in his diaper a lot of times now...just a stubborn one who wants to still use his diaper, but hey, we're taking it at his pace to see when he is comfortable with the potty. Hope this helps and best wishes to you all with the busy times ahead!
