Need advice on baby registry

My husband and I live in a small one bedroom apartment. We plan to move eventually but we can’t at the moment. I kept this in mind when selecting items for my baby registry which I plan to share with family and friends soon. Our baby is due January.

My mom has a habit of overdoing it and buying a lot of cutesy and often useless things she likes for my sisters daughter. My baby will be her second grandchild so I expect a similar approach.

Since we don’t have a lot of space, I feel like saying upfront “we only want things in the registry. If you don’t wanna get us anything from here, that’s fine. But we really don’t want anything outside of it.”

That sounds super bitchy, I know, but my mom is the kind of person where you have to set boundaries and lay down the law or she doesn’t take you seriously.

Is this a bad approach? Is it wrong of me to say this? We get stuff we didn’t ask for, I plan to donate it because I’m not joking when I say we just don’t have room now. Our registry is also a list for me to get stuff from—not just other people. I like to plan and be thorough.
