Best boy potty?

mo

My 18 month old keeps taking his diaper off and has stood up and peed outside his crib the last 2 days lol🤦‍♀️ sooo I think it’s time to start potty training!

Wondering if anyone has any recommendations for potty’s that work best for boys! Would like to avoid as much mess as possible lol

these are the 3 I’m looking at, open to other suggestions as well:)
