Mommy rant

I'm pregnant with my first child so of course my husband and I started buying stuff, well my mil told me to not buy anything else so everyone could get stuff we needed for the baby shower. I already bought the pack and play and wanted the travel system that matched, well someone gave her a travel system that she plans to give me but it's not the one I want. I don't want to seem ungrateful by telling her I don't want it, but I'd rather get the one I want myself that matches everything
