I feel bad

My mother in law and sister in law offered to buy our car seat and stroller set. We agreed but my husband told them I was going to choose which one I’d like for our daughter. & of course to make sure it was a good size for me to travel with her bc I am small woman and didn’t want anything to big or bulky. He sent a picture of the one we chose and they came back with a completely different one. I feel so bad bc I didn’t like it and makes me feel ungrateful. I really do appreciate it but don’t understand why they went and chose the stroller/car seat for us.. now I feel like I have to keep it but I’m really unhappy about it. Has anyone experienced this?
