Annoying as shit

Wanna know what annoys me. When people who hsve no kids tell me what to do or don't be this or that. I had my baby shower yesterday and I was texting a few people that I know if I didn't or dont they will be like she's so selfish or gready or ungreatful. So I texted my bfs sister and thanked her agian.

She replys with np. Just don't be gready or stingy with my nephew ;) and this isnt the 1st nor 2nd time this is like the 3rd or 4th maybe even 5th time she's said that. it's like

If I don't want vistors over certain days than I'm not gonna have people over. And I know its gonna be a fight. If I wanna be gready and enjoy my baby I'm gonna and I don't think I'm wrong for that. I'm the one carrying him , giving birth to him , etc she use to do it with my stepkids telling me how to raise them

Advice?

Ftm plz no bashing
