Does this annoy anyone else?

Yesterday my friend and her 5month old daughter came over. My 8yr old daughter was just cranky and in a mood 😑 She rolled her eyes at me,gave me attitude and just fought me on everything! My friend who is a new Mom kept making comments like "Sadie would NEVER treat me like that", " You need to be more disciplined" and she kept trying to offer me advice on situations she's never been in. At one point my daughter went into the pantry and poured her self a bowl of cereal my friend said " Sadie won't be eating crap like that,too sugary"...I've known her for 5 yrs and she's never tried giving me advice. Im just so annoyed that this New Mom of only 5months was being so Judgy and thinking her and her daughter will just have this perfect relationship and life together. Would this annoy anyone else or am I over reacting. She's suppose to be coming over for a BBQ Saturday but honestly I don't want her their now....
