Hi L.!
I know that you said you don't think it's the brand, but the few things I would recommend are as follow:
1. Use a bottle similar to your breast shape.
2. Warm the bottle to about the same temp as your breast milk.
3. You and your 3 ½ years old should LEAVE THE HOUSE, and let dad feed. Maybe take him for a walk around the block. This way you are spending special time with him, and the baby can’t hear or see you to “rescue” her from that “mean old bottle”, so to say.
My son took a LONG time to except a bottle from me, but from my husband, it took about a, week if I recall. It WILL be stressful to you, Daddy, AND the baby, but in the end, it will be helpful to all of you as well. Besides, even a baby won’t starve for missing one meal. Even if she won’t take it the first time, she will eventually. I know it’s hard, but sometimes the best thing you can do is just not give in. (Trust me, I know this is hard! I still have trouble standing firm on what I’ve said, and our son is a little over 2 now.)
Hope this helps! :-)

P.S. Don't let others tell you what's best for your child. I breastfed for 17 months, but my sister-in-law only did it for 3 months. Both of us have happy, healthy, well balanced children. If your ready to ween, you do it. YOU are the mom. Trust your instincts and do what YOU know is best for YOUR child!
