Welcome to YT!!
I'm feeding TOTW Pacific Stream formula right now and all five of mine love it. I think it's an excellent food, but the most important thing is that your baby likes and will eat it.
I wouldn't recommend giving her the Karo unless she needs it. Try to let the food provide everything she needs. Just feed her often, or free feed her, to keep her blood sugar levels even.
I bet you don't have to break up her food for very much longer. Once she puts on some weight and gains strength she'll probably be able to crunch it up on her own. I was amazed watching Tate eat when he was such a tiny puppy.
Congratulations on your new baby! We'd love to see some pictures.
