If you figure it out, be sure to let me know. We are going through the exact same thing here. She will only take 2-3 oz of her bottle, then bite it. If I add it to cereal, we get the whole thing down. If I don’t offer her cereal, she doesn’t seem to care and waits another four hours to eat very little. I’m thinking teething since she has none yet and she keeps biting me and generally fussiness. Ugh.
