Diapers...don't get me started!

As is probably obvious, I am a mother. A mother to an almost 5 year old son and a 5 month old daughter. Now when I had my daughter (4 1/2 years after having my son) I was amazed at the advances in baby gear!! The strollers are so much more versatile and light weight, the diaper bags now look like hip Gucci bags, the carseats have side impact protectors, you name it, they probably have it. But here is the odd thing, there has obviously been no advances in diapers. In fact, I am pretty sure that disposable diapers of today are hardly better than the ones used in the 70's!! How do I know this?? I know this because my beautiful, sweet, precious baby girl shoots crap straight up the back of her outfit at least every other day!! Why? Because diapers are not fitted around the top! Not to say that the fittings around the legs don't leak, cause they do, but for some reason all it takes is for the child to be sitting in any upright position when said poop happens and instead of being absorbed or dispersing in the lower part of the diaper, it shoots straight up the back, over the top and soils that sweet, pink and frilly onesie (at the most inopportune time, of course)! i just find it odd that we can make cars that can park themselves, but we CANNOT seem to make a diaper that can actually contain baby shit!! It's not like there isn't a market for such an item. Ask any haggard mother who has been in a restaurant or store and picked up her adorable child only to realize that not only the child, but the carseat and herself are covered in poop and I'm sure she would tell you in no uncertain terms that she would practically KILL to have a diaper that worked! But I don't think it will be something that I will see in my lifetime. Diaper companies don't feel the need to truly improve the diaper since we will buy them regardless. I mean what else are we gonna do? I suppose I could use cloth diapers, maybe they actual contain biohazardous waste better than disposables, but then there is the downside of having to wash them!! It is bad enough washing the nasty, poo-stained onesies! I would surely wretch if I had to wash cloth diapers! So the cycle will continue, I will continue using disposable diapers, and my daughter will continue ruining onesies and that will be my life until she learns how to poop in a toilet!
