Best Bottom Trainer Review

Potty training.  The bane of my existence.  When it’s time for potty training (or potty learning, whatever), getting the right pair of underwear for your toddler can make all the difference.  For Norton, I found that the Best Bottom trainer was a great trainer.

Best Bottom Trainer Style

The Best Bottom trainer is a sized trainer that looks a lot like underwear on the outside.  The inside is lined with PUL and the trainer is designed to be used with particular inserts by Best Bottom.  Another great thing is that they are made in the USA!

What’s Awesome About the Best Bottom Trainer

The Best Bottom trainer is often sold in a pack with three feel wet inserts.  However, just because your little one is begging to wear underwear, that doesn’t mean that he necessarily gets the idea.  (I know that Norton didn’t.)  And sometimes, it’s good to have extra wetness protection.  With that in mind, you can use the Best Bottom diaper inserts in sizes small and medium.  It’s also possible to just get through the entire day in one trainer, particularly if you change inserts.Best Bottom Trainer Review (Cloth Diaper Addicts)

The design also makes it easy for your toddler to pull the underwear up and down.  The lack of side snaps make it feel more like underwear and less like a diaper to my boy.  I find the price (typically around $25 CDN/$23 USD) to be pretty reasonable, especially considering how many uses you can get out of the Best Bottom Trainer.

What’s Not Awesome About the Best Bottom Trainer

There are very few colors in the Best Bottom Trainer line up: blue, green, pink, purple, and white.  I’d love to see more fun colors and prints involved!  I like to match my son’s underwear to his clothing just as much as I enjoyed matching his diapers.  The lack of side snapping, while awesome for feeling like underwear, sucks if there’s a poo.  I also find that the fabric flap can get wet on my son, which leads to me putting a shell in the wet bag earlier than planned.  I’m also not too keen on the instructions calling for a warm wash instead of a hot wash.  That means that I either a.) have to do a separate load with my cloth diaper safe detergent or b.) have to wash them on the “wrong” setting.  I wash mine on hot, anyway, because washing something that my kid defecates in on warm is just… gross.

In a Nutshell?

The Best Bottom Trainer isn’t perfect, but it’s my absolute favorite trainer to date.  And it’s one of Norton’s too.  If it only had a picture of Lightening McQueen, he’d never want to wear anything else.

Have you used the Best Bottom trainer?

  1. Thanks for linking, Suzi! Great post. I’ve not tried these trainers yet, but it looks like they’d be a good option for my youngest daughter!

  3. I’ve been wanting to try these for a while but the lack of side snaps is really holding me back. I’m potty training TWO toddlers right now, and the occasional soft, yukky toddler poo is just NOT something I want to deal with right now. Anything that you have to pull down inevitably leaves a big mess on their legs as you take it off….

    • Ugh. We hate side snaps because Norton calls them diapers. Fortunately, he does not have soft poo. Ever. (Really fortunate because he will not poop on the potty.)

  4. AH! Potty Training. The worst. Thanks for sharing this option in detail. 🙂

  5. would these be absorbent enough for a night trainer? My son is not a heavy wetter at night, he stays dry about 75% of the time but still wets occasionally.

    • It depends. You can put a medium Best Bottom insert in the trainer with no problem. If he trickles at night, wakes up, and then runs to the bathroom, no problem. If he’s even a moderate wetter, he’d do okay with the medium diaper insert.

    like that they are sold in packs of 3

  7. I love those inserts! I love that it comes with 3 and they are just cute!

  8. I love the best bottom trainers! Yes, the soft poos are awful, but I bought two overnight inserts, and they do the trick! 🙂

  9. Jennifer A. says:

    Thank you for the review! This will really come in handy when we start potty training! I like the way the “Best Bottom” system works, and the inserts for the potty training system are adorable! 🙂

  10. I’ve tried several trainers but these are next on my list. Thanks for the honest review.

  11. I love Best Bottom diapers and have been eyeing these for when my daughter starts potty training (hopefully soon). Thanks for the review, it was helpful!
