I bought this for my already potty trained 3 year old who still wets at night. I love that it's not a disposable and is similar to cloth diapering. The fit on her is very similar to the 4.0's. If she were potty training I can see how these would be fairly easy to use, especially since the insert velcros in. I think this system would have been expensive if i had used it for potty training since we had more than 3 accidents a day in the beginning (I potty train with good ole Gerber thick cotton training pants and plastic pants). However, for night time use I use 3 inserts and still have a leak sometimes. Also, I like to wash my dipes every other day and if I'm using all three inserts in one night then I have to wash more frequently. So I used my 4.0 adjustable inserts all the way unsnapped and put them inside of an insert sock and I really like that. I use the sock too even when I use the flip inserts. It really helps keep all of the inserts in place and together, plus keeps the moisture from sitting on her bottom area all night. All in all, I would probably recommend this as a decent "pull-ups" replacement and will probably use it in conjuction with cotton underwear and plastic pants when i potty train my sone. You just have to figure out what works for you and your little one.


I bought only the shell, because I diaper with the flip system and have almost 100 of those inserts not to mention some prefolds and flats. Everything seems to fit and work just fine inside the trainer shell. Even without the velcro everything stays in place ok. If it really bothers me I might buy some velcro and sew it to some of my inserts. So far - not bothersome enough to be worth the effort. I bought this for my 7 year old daughter who still wets almost every night. She is just now becoming aware (after summer camp) that wearing a "diaper" at night is not cool. And I was long tired of pullups. Every training pant I tried before either got disgusting, because the absorbent material was sewn to the waterproofing and grown up pee really gets it smelling foul, or was woefully inadequate when it came to absorbing and stopping leaks. I bought the lovelace pattern and she loved them. I bought the disposable inserts for her to take to camp and she is very relieved to have a "nighttime underwear" to take to camp. We've been using them a couple weeks. Note - we already don't allow liquids after dinner and she goes to the bathroom right before bed to minimize whatever mess may occur. So far - my flip microfiber inserts seem to do an ok job. Some nights I wish I had put a doubler in there, because some wetness has gotten on her pjs and sheet. But it is a small amount that can be easily managed. I have noticed that she seems to wet much less often. I don't know if the feel of it wakes her up or what. I haven't used the disposable one yet. My only complaint (which is really more of a beg) is that these BARELY fit her. PLEASE PLEASE make larger side panels Cottonbabies!! Otherwise I am going to have to brush up on my sewing skills, which aren't that good to begin with.


I agree that at the time it was unclear that the inserts were separate since there was no "kit" then. I figured they were separate based on pricing, but I also thought my existing stay-dry inserts would be compatible. Booo Cottonbabies for making us rebuy the system. I think the shell is the same high quality I've come to expect with flip, but even the smallest setting is a little saggy on my nearly 2yo. I tried the shell out with the smaller inserts from my BGs since they hook the velcro. However, it's not easy to incorporate poop liners which we always use because baby doesn't keep to a poop schedule. This would probably be a good system for use once baby is already having some successes with potty training, but by then, I'll have found something else. The flip trainer isn't the easy transition I thought it would be. I'll look around for other products and may bite the bullet and get a 3 pack of inserts to try out, but I'm not really optimistic for version 1.0. CB does make great strides without even advertising them sometimes, so make sure you read current reviews.


i feel like i didn't receive what I was told I would be getting based on the product description of this training diaper. There's nothing in the product desciption that says the pads are sold separately. I'm upset that I have to pay twice the amount of the diaper to get pads to go with it.
