I just transitioned my daughter to size 1 Pampers last week and every time she pees she soaks right through them. Its not leaking through the sides or back, its literally soaking through the diaper. Its not an exorbitant amount of pee either. I'm changing her clothes several times a day because of this. We didn't have this problem with Pampers NB, what could be causing this? She is 12.5 pounds and they seem to fit her fine. I bought an economy size so I'm hoping to resolve this because I don't want to waste all the remaining diapers!
