BabyBjörn Toilet Trainer, White/Gray

Across the reviewers we read, the BabyBjörn Toilet Trainer is the consensus pick once a toddler is ready to move from a floor potty to the adult toilet. Verified-purchase reviewers at Target describe it as exceptionally stable, and parents in r/toddlers say the ergonomic shape and adjustable fit let kids climb on and off independently. The same high-trust r/toddlers thread that praised the BabyBjörn floor potty's splash guard names this insert as the best option for boys for the same reason.

Its strongest practical advantage in the threads we read is that it stays put. r/ECers commenters describe the BabyBjörn line as reliably stable, and r/bigbabiesandkids reviewers note it feels secure enough that even larger toddlers don't slide. The trade-off is price, at roughly $40 it's among the more expensive inserts in the category, and unlike folding travel seats it doesn't pack down for trips.

Reviewers do flag one general concern about hard plastic inserts: a cautionary r/toddlers post about a different brand describes a pinching injury, which is a reminder that supervision and proper fit matter regardless of brand. That concern was not directed at this product, but it's worth noting given the category.
