I thought I would give these a try after hearing about them via the netmums website. These are a small triangular pad (rather like a sanitary pad but with a green cover) with an ashesive strip to place inside underwear. It will hold a fair amount of liquid, so does the job well enough.
I have these on a repeat subscription order, and will probably continue to use them. Cost wise there isn't a great deal of difference between these and Huggies pullups (if you use 2 pads per pants). However the advantage with these as that it uses the childs own underwear, something to think about if going to school or nursery.
Because these are small pads you neeed to fit one or two pads (front and/or back) depending on the type of accident you are trying to avoid.
How many you go though will depend on the type of accidents that are most frequent so please bear in mind when you consider the quantity per box, especially if you are using these pads front and back each time.
Please be aware these are not really a substitute for pullups, so if your child is not yet at least partially toilet trained, these are not for you.
I would say these will only be suitable for small or infrequent accidents.
To sum up, a good idea, but personally I would have preferred a larger, single shaped pad.
