Some people have complained about the extra padding making them less effective, but my carpets and I thank you Carter's!  First off, they are adorable!  My daughter just loves the prints and I think they are pretty cute too.  She prefers these prints to the Gerber ones and they fit her better.  She started wearing the 18 month version at 17 months (she was 22 lbs) and then I recently ordered 2 more sets and they still fit her perfectly, a little better now than at 17 months (she is 21 months, 23.5 lbs).  I have been attempting to potty train her since 16 months and had started to see success at 17 months, but then she went back to daycare and couldn't run around bare bottomed and have accidents anymore.  Since we only had two pairs of these at home, when she was in the other brand (Gerber), she would end up with pee everywhere and we put it all on the back burner until 2 weeks ago.  I ordered more of these and now she is pretty much trained!!!!  She doesn't like it when she runs out of these due to accidents.  I don't think that was the secret to her success, but the fact they appeal to her, fit well, and she wants to keep them dry have helped considerably!  And her father and I appreciated that we can have our area rug out for the winter and don't have to constantly scrub pee out of it!  These are expensive, but I think well worth the price (and a lot cheaper than some of the fancier ones).  My only complaint is that they don't have more patterns.  These are adorable, but I would like to see some more variety too.
