difficult one this, you dont want her to think you are questioning her parenting skills, which you are, but with the best intentions. How about getting her a baby meal planning book, or a book about weaning just to try and get her ont he right track. ? If you go about it the right way it will look like you are taking a healthy interest in her baby and trying to help not interfere. I hope you sort this one out. If she is not doing anything dangerous it may be best to leave her to get on with it though.
