Until Luvs came out with the bear hug stretch the diaper didn't fit perfectly around my two boys waists. I always had to buy one size bigger and let that work. I was excited when the stretch came out because Luvs is the one diaper that both of my children don't have any problems with.
I tried every diaper and nothing worked as well. They either spilled out of the back or front or the sides. The Luv diaper held it's own. Nothing leaked, even the diarrhea. My first son got very ill as a baby and had constant diarrhea for about a month. Luvs saved many outfits!
The price is about even with other brands of disposable diapers and if you sign up for coupons it helps a lot. For a box of about 92 size 4 diapers it costs $19.99, with each size there are more or less diapers per box. The only thing left to say is that I love Luvs!
