Pampers easy up pants are designed to be 'pull on nappies' and therefor as absorbant etc as 'normal' nappies
Many shops (tesco / asda etc) do there own brands of pull on NAPPIES that arnt training pants
Huggies do huggies convertables which can go on as a nappy or a 'pant' and are also technically nappies which pull up as well as a bonus.
Then there are 'huggies pull ups' these are potty training pants.... designed to be used by children learning to potty train...
they are therefor NOT as absorbant and not desigend to cope with lots of wees as normal nappies are...
many shops have there own brand training pants as well
(in reality these pull up training pants feel 'dry' like disposbale nappies, and toddlers often dont realise the difference, therefor i personally think they dont help with toilet training at all!)
Now pamper have there own traing pant (feel and learn) which are like huggies oull ups but feel wet (MUST be better than disposable training pants that 'feel dry', but i still convincec proper pants that get wet, is the real way to potty train a child, but thats not the point!)
hope thats a clear enough explanation...
Oh and drynites.... they are pull on NAPPIES for older children who wet the bed and therefore need a larger nappy that absorbs lots of wee and feels dry...
if you have a heavy wetter and put them in (huggies) pull ups they often leak at night... where as a larger size 6 nappy, or a huggies dry night pant is less likely to leak on a 4+ year old
hope that helps!!!
