does anyone feel like they get undermined as a mom?

so i’m 21 and my son will be 6 months on thursday. well everytime i come visit my dad and grandma they’ll be holding him, playing w him, whatever and give him some type of food. last time i was over, my dad had a popsicle and my dad asked me “can he try some?” and my grandma goes “go ahead give him some” before i could even say anything like WHAT? then today i went to the bathroom and when i came back out he was getting fed soup which i didn’t give the go ahead for that. i would probably let him have those things if you look at me as his MOM and ask me “can i give him a little bit?” but like wtF. anyone else deal w this?
