Thankfully there is more than one way to do something right. Especially with babies and children, it can seem overwhelming if you feel you aren't doing everything exactly per the book.
But the question is, who wrote the book? As a mother, or a parent, you get to write the book for your child with them. And no one else. You get to decide what is right for your child based off your experience, your knowledge, and what is true for you. And that is the only right there is.
