People already telling me how to be a mom

I have a few friends that have had babies recently and are giving me all these tips which is appreciated and stuff but I have this one girl in particular that just won't stop. Everyday she tells me how she does things and tells me if I don't do it that way that my baby will suffer and it's really annoying now. I am a first time mother but I know that I'll be fine and if I have questions I will ask. I don't know how to tell her to stop it without saying it and sounding mean and I don't want to hurt her feelings but she really ain't that great of a mama and I doubt I'll listen to anything she says because I have had multiple children in my care from newborn up to 6 years and she keeps telling me how I didn't do things with those kids right and yada yada yada. And I'd say I did a good job because I was very loving and gentle and patient and as soon as her 2 month starts whimpering even the slightest bit she will quite loudly tell him to "shut up dude" or something along those lines. It's very annoying but I still wanna be friends I just don't need her advice.
