Target practice

Andy is too young for proper potty training, but I'm putting him on his potty before his bath just to get him use to the concept. Usually, nothing much happens, but the idea is to get him comfortable. Then night before last, he actually decided to pee while on the potty. That would have been great, but the potty I have is apparently not designed for boys since he sprayed the entire wall. Having no experience with boys, I am not sure if I need a new potty or need to practice "tucking" once I sit him down. I can tell already this is going to be a long process.
