I’m one of those people who exhausts every possible avenue to find the answers before going to an adult for them.
That is why we found “The Baby Book” (of the Sears parenting series) to be a handy reference (the book covers topics from birth to two years). While the attachment approach isn’t for everyone (and we certainly didn’t follow every single suggestion despite being pro-breastfeeding and into baby wearing, etc...), the basic baby care and developmental information is extremely useful. We were able to do a lot of successful troubleshooting at home with this book as a reference (with the web as backup here and there) and it saved us many unnecessary trips to the doctor's office.
