However, with the development of modern disposable diapers in perfect sizes and pull up versions just like underwear, the comfort of a wet diaper has improved dramatically. Thus making the child less motivated to get out of diapers. For many parents there are various motivators to have their child potty trained. The longer the child is in diapers the more expensive it becomes. Another child on the way two in diapers is also a strong motivator.
Many preschools also have a requirement that the child is potty trained prior to enrollment.
Many parents choose to potty train in the spring and the summer, simply because it is less clothes to take off for every trip to the potty. This means that spring is the peak season for buying potty training equipment. The floor models are either small one-piece units or larger models with a loose chamber for ease of emptying and cleaning. The larger models are usually higher and give the child a more comfortable sitting position, especially if it has a nicely contoured seat with a good back support. Remember that the child will be sitting for quite long periods in the beginning before they master the technique, so comfort is important.
