Yes, I think disposable diapers make potty training harder. If you look at the average age a child was potty trained even just a generation ago, you can see that kids now take a lot longer to give up the diaper in exchange for using the potty. Lets take a look at some of the reasons that modern disposable diapers make it harder for your child to be potty trained and what you can do to make it easier on him or her.
One of the biggest improvements that has been made in the disposable diaper industry over the last decade, is how quickly the diapers absorb moisture. The obvious advantage of this is that it keeps babys skin try and prevents diaper rash. The disadvantage is that your child does not feel when he or she gets wet. There is no uncomfortable wet and squishy thing hanging around his bottom. Everything is perfectly dry and comfortable. So why should your child bother with a potty if there is nothing wrong with peeing and pooping in his diaper.
The disposable diaper industry has of course picked up on this fact and is not catering to the parents of 3 to 5 year olds. We see pictures of children in this age group on diaper packages, baby and parenting magazines...
