Letting family babysit 10 week old baby

So I have yet to let anyone babysit my 10 week old baby boy. I'm just not ready yet, and I will let people know when I'm good and ready to have people watch him. But my husband's family asks probably once every two weeks if they can watch him. My husband and I have come up with a variety of excuses as to why they don't need to. It's getting annoying and it stresses me out! Keep in mind that he is ebf and he still doesn't have a reliable schedule to when he wants to eat. I refuse to give him a bottle at this point and I hate pumping, so I'm his only food source. Plus, I really don't trust people with him yet. He's high maintenance (as are most babies) and I know what he needs better than anyone else. He's also my first child and my rainbow baby, so I'm a little protective! I will let people babysit him at some point, obviously, but I'm not even close to ready. So I ask is this normal to not want people to babysit? And am I being rude about not letting my husbands family watch him?
