You need to sit her down and tell her exactly how you feel. If she is truly your friend she will understand. I told mine “I appreciate the advice and the assitance. Really I do. But lately it has been getting out of hand. Could you please stop with the advice. Yes I might make mistakes with my kids, but they are my kids and my mistakes to make.”

She looked at me and said FINALLY.

I know what you mean, and its hard to tell someone who you love someone who is your friend to BUTT out of your life.
Be calm and tell her nicely that you appreciate all she is doing for you but there are somethings that you need her to do less.
Explain to her that you understand that she is trying to help, but each child is different and each child responds differently to different things. There is no Tried and true book on raising kids.
While you can learn alot from a great many books, there is no set advice you MUST abide by other that state and federal laws.
Explain to her that the book she is expecting you to take heradvice from, is from a woman who has never married, has no true children of her own stepchildren or biological kids.
Explain to her that if she feels the need to give you parenting advice then you would more readily accept it if the source were from someone who were ACTUAL PARENTS!!!!
Do try to be calm however hard it may be, friendships are a dime a doezon, but true friends only come once or twice in a lifetime. In time you will learn to place these types of people on auto ignore, you hear them but you dont listen. Use your own best judgment for your child, along with your peditrican.. that should do you.

Sit down with your friend (someplace fairly public so that you dont have to feel bad about walking away) and tell her ” I appreciate that you have taken such an interest in parenting, but no book will ever teach you what real life can. Please dont pass on your knowledge anymore until you’ve been able to give it a test run with your own kids. Thanks for understanding.” Then get up and walk away. Its direct and to the point without being mean and the fact that you get up and walk away tells her that you are not inviting discussion on the matter.

Good Luck.

You may decide to just nod and do what you know is the right thing to do; just keep silent and allow them to rant on and on while you do what you know is the right thing to do.

You can look them straight in the eye whenever they start and give them a look that will tell them their advice is not needed/ welcome .

You can find some “neutral” time (when they’re not giving you the advice) and tell them you appreciate their interest and concern for you to do a good job of parenting but would like for them to be a little more understanding of your need to get it right at your own pace, and that their nattering is just a wee bit unhelpful.

OR you could hold the same kind of meeting and tell them to please leave you alone.

If all these do not work, you can tell a mutual friend who may be able to mediate in the ’stalemate’.

If all these fail, then keep away from them until they come to their senses!!

I want to add that in most case such people think they’re trying to help, so be considerate and try all means of approach to get them to understand how you feel.

All the best!!

And repeat it every time she tries to give you parenting advice. Pretty soon she’ll get tired of hearing it, and STFU.

You might want to tone it down a little but that should do the trick!
