Reddit mentions of Gerber Baby Boys' 4 Pack Training Pants Toddler Underwear

I recently went out and bought several types of trainers/potty pants so that I could compare them before I bought into one type. I'm at a similar point as you are where my little guy has been going on the potty for quite a while and doesn't 'produce' much in his diaper so the girl at the store said it's a perfect time to get him into trainers. Keep in mind that the whole point of the trainer is that the baby feels the wetness when they have an accident so be prepared for some spills. You could limit the spills by putting a diaper cover over the trainers.

Here are my fave in order:
Blueberry:

These are great when we're hanging out around the house. If he has an accident they tend not to leak right through. They have nice thickness to them, and I like to let him wear them without a waterproof cover. They have some great designs too so I let him run around the house in just these on hot days.

Bummis:

These potty pants are what they call an all-in-one...they have a waterproof cover so they'll hold leaks in better. I really like how streamlined these are and the inner fabrics are hemp and cotton.

Under the Nile: (http://www.amazon.com/Under-Nile-Organic-Training-Pants/dp/B00FU9H25M/ref=sr_1_7?ie=UTF8&qid=1404879318&sr=8-7&keywords=under+the+nile+training+pants)
These are almost like regular undies and at this point I find they leak too much for our needs. In the future I can see us using these more since they're adorable, very soft and organic cotton. They should have a waterproof cover over them but the Bummis Pull-On cover (http://www.amazon.com/Bummis-Diaper-Cover-Large-pounds/dp/B008PTZ170/ref=sr_1_1?s=baby-products&ie=UTF8&qid=1404879142&sr=1-1&keywords=bummis+pull+on+diaper+cover) feels very rubbery and I don't like to keep him in it all day.

Gerber:
(http://www.amazon.com/Gerber-Boys-Pack-Sports-Training/dp/B00AT90J5S/ref=sr_1_2?ie=UTF8&qid=1404879489&sr=8-2&keywords=gerber+training+pants)
These are in the same boat as the previous ones...they're just too thin for his needs right now BUT they're a great price and all cotton. I can see us using these a lot once he's better trained.

Just a note...the girl helping me at the store mentioned that even with the waterproof covers these are not really meant for naps or car rides. I would agree. I still put him in his regular diaper for those. When we're hanging around the house though I just make sure to put him on the potty after every meal and nap (or whenever he points) and on those days he has very few accidents.

Excuse the long post...hope it helps...and good luck!
