I loved the pampers sensitive and i used the playtex but with the wide nipples not the drop ins and they worked great for me.
I use luvs they are cheap and work great, and I used to use the Playtex bottles didn't really like them the best one I think are dr browns
I don't really know anything about those brands/choices... We're planning on breastfeding & using reusable diapers. The reusable diapers make more sense financially... You can spend an initial $100-$200 and don't really have to buy diapers after that as long as you keep them in rotation. We just don't really have the disposable income or trash services for the disposable diapers.
Just a different perspective for ya! :)
I know two people whos babies now have to use powder puppy formula (yes dog food) bc the bottles with the inserts dont function the right way for the baby to be able to breathe and eat. They are horrible from what ive seen, and the babies now have liquid in their lungs, severe colic, and cant laugh without gurgling something up.
As for the diapers I couldnt tell you. Ive been told by everyone it is trial and error so I have decided to put money on a card instead of buying a brand of diapers that I may end up not needing, then buying diapers as I go with the saved up money.
