I have a 17 month old son, and now a 1 month old daughter - we go through diapers like crazy in our house! When I was expecting my first child, I wanted a diaper that was eco-friendly, hypoallergenic, and made without all the crazy chemicals. (While these aren't perfectly eco-friendly) Pampers is a reputable brand, I work in the children's hospital and this is the brand we give to our patients - I was happy to find the Pampers Pure because they contain less ingredients than the regular Pampers.I have used this brand from day one for my son, we never had any major problems with leaks, whenever he would leak it was time to size up. There is one issue I have with the diaper as we have sized up over the years (he is in size 5 now) and that is how long the diapers are. These are larger than the regular Pampers, and several other diaper brands I have seen out there. You may be thinking, well larger is better to hold the big messes - and I would agree except that it awkwardly holds in the bowel movements and often times they will get too bottom heavy and start sliding down. Its not a huge deal, we have used this brand for a year and a half and started my daughter in them as well. I am going to experiment a bit and buy the Honest brand for the next month, as I put a trial/sample diaper on my daughter the other day and loved that they fit her around well, and did not ride high on her belly button or create a bulge in the back.
