OP, it sounds like you're doing great with attachment parenting, it sounds like your kids are doing great - no need to compare yours with others.
Developmentally, sometimes they'll be ahead, sometimes they'll be behind. It's true when they're younger, and will be true when they're older.
Focus on your own relationships, enjoy the moments you spend with them. Teach your kids how to appreciate how precious these moments are - love them so they learn how to love. This will probably matter more than whether or not you're doing AP, or whatever else parenting style.
