Can i vent: So im watching tv in the living room of my house which i never do with my 2 month old son on my lap, he started getting fussy because it was around his naptime so instead of going in my room to nurse my son like i always do i decided to nurse him in the spot that i was sitting in. My brother walks out the kitchen and says "ugh come on Chaz put that away or cover up" and proceeds to beg me to cover up and tell me hes offended. We went back and forth about why i should cover up for a while. I then told him to cover his face while he was eating the chips he walked out the kitchen with and continued to nurse my son. I also want to put out there my stepfather walked in in the mist of our argument and said nothing about me feeding my child and that he's actually had plenty of convos with me while i was nursing my son and it never bothered him. Im still upset and this happened 30 mins ago
