Would you be upset..

So to start off, I am a FTM. My LO is 6 weeks now. I have a bestfriend who i love and I know she would do absolutely anything for me. She is also the godmommy of my baby. Anyways, every time she comes over she constantly holds the baby and picks him up. (I admit I get a little jealous). But lately shes been telling me things like "you need to clip his nails they're long" or "make sure when you change his diaper you wipe in between here" just a side note, shes never had kids and does not have kids. I understand shes just trying to be helpful. But today through me over the edge. Today she came over in the morning to finish painting the room for the baby. My boyfriends mom had stayed over last night to help us so we could get some sleep. So she was on the couch with the baby and let my friend in. Meanwhile me and my boyfriend are still laying in bed.. my boyfriend gets up and to go make a coffee. When he comes back in the room, I tell him to go get the baby and that I want him. He says "no. Hes cranky and jen (my friend) is with him right now"

Why do I feel so upset by this.? I I instantly got mad and told my bf that I am his mother..
