T.G.
you shouldn't be feeding formula through a bottle or cup. feed it to her in a bowl mixed with the Gerber cereals. She will feel like a big girl and hopefully embrace the new experience. I have five kids and let me tell you, they ALL were different. But one thing that remained the same, feeding habits. Introduce her to other foods if you already haven't and just look how much her attitude changes. Also, tell her how much of a big girl she is by eating out of a bowl just like mommy does. I started feeding formula with cereal to my babies at the 4 months old and feeding jarred food at 5 months. Now 17, 13, 11, 10 & 8, they all love vegetables, even brussle sprouts.
