Lady was a strange picky eater as well at first until I adopted the method Karlin suggested. It really does work like a charm. My mother in law ignored this method for a while and finally tried it and it's worked for her as well. They are little gluttons and will not go starving. They soon learn they better eat when it's offered or they will stay hungry!
Lady gets 1/2 cup twice a day at the exact same time every day. She knows when her meal time is. She goes to her food cart and bites it. HA! She was at 1/4 cup twice a day and when she reached 6 months we upped her to the 1/2 cup twice a day. We are pretty strict with it and give her training treats are the 1/2 calorie bites. She gets bully sticks whenever. Haven't made it to he home cooked meals yet. Don't know that I will. I need to read more on it.
She is 7 months @ 10.3 lbs.
