Gracie HATED her bag at first. I started using it when she was about 3 months old and she would fight like crazy. We had an unexpected move right after we got her and had to be out of our house a lot for it to be shown so I REALLY needed her in her bag. I carried treats in a little container and would give her one every few minutes or so at first then gradually tapered off. She ended up loving her bag and to this day goes crazy with excitement every time I bring it out. Good luck!
