I am so frustrated of everyone giving me free advices as to how and what to do for my baby. Even if if am doing the right way someone or the other has to comment to do it their way. I am tried! What do I do?

I feel that every time someone tells me something, there's always something to learn. Whether it's new knowledge, reassuring that what you are doing is right, or just plain repetition or nonsense. It's up to you to absorb what works for you. Don't think of them as criticism. It's not so frustrating this way.
