ebf baby not wanting to eat

My 3 month old, up until last night, is on a 3 hour schedule. Today she will cry at the 3 hour mark but won't eat a and ends up going back to bed. She has been going 6 hours and when I gave her some expressed milk she only at 4 oz. When is the time to be concerned?

Also she has no fever and her only symptom is that she is more talkative.

If she's not hungry and not sick, I wouldn't worry about it. Maybe you should try spacing the feedings out a bit more. Babies don't have a good concept of time. They eat when they're hungry and if they aren't hungry, it's almost impossible to get them to eat.

We feed on demand she's just not demanding today. Didn't know how long I should let her go before I should start to worry about some underlying cause

Quoting Renea2009:" We feed on demand she's just not demanding today. Didn't know how long I should let her go before I should start to worry about some underlying cause"

I would say longer than 24 hours. Is she teething at all? It's not all that unusual for the babies to have 'off' days too sometimes. Sometimes they can have nursing strikes. Have you looked at http://kellymom.com/ before? It's an awesome site that has some tips and tricks on how to handle all of this breastfeeding stuff. I remember being on there a while back when one of my kids wasn't eating like he was suppose to.
