I have a 18 week old who for the past 3 days won't take more than 3 or 4 ounces in the morning. Which then messes up the 9 am nap. she wakes up hungry. the rest of the day she takes 6-8 ounces. She gets a dream feed at 1045 PM. I would assume she is starving in the morning. Today I tried to wait 15 min to feed her but still same result.
