I think as long as it's not upsetting you to think this way (it's not making you anxious I hope?) then I think it's a really good thing, it means you are a protective, fierce, loving lioness who is padding around flattening the grass and getting everything ready for her precious cub, and everyone else can back off. That's awesome.
Don't be afraid to be assertive once your baby arrives. Some people dismiss the mother as soon as the baby arrives. I was appalled at the attitudes within my in laws side of the family when I was expecting DD. Every single one of them at one time or another told me that once the baby arrived it 'wouldn't be about me'. I'm quite a pushover in some ways anyway, and quite introverted. I have no problem with the spotlight not being on me. I don't know why people say these things, it was very definitely a way of saying, once you've produced the baby you are totally done, see ya.
In any case, once the baby had arrived she wanted me, no shit. Guess it turned out to be a little bit about me after all. This wonderful little creature that I'd carried for 9 months adored me from the get go, and I her.
Pad down your grass and don't worry about grabby relatives. Everyone will chill out once the baby has been here longer than five minutes and if they aren't giving you the room you need to feed and care for your little one, don't be afraid to ask them to give you some room.
