My LO has had some really liquidy poops the last few days. I thought it would go away, but it hasn't yet. I don't really think it's diarrhea because she is still only going once or twice a day and eating normally. I figured if it was diarrhea she would be going a lot more often then once a day!?! I am going to call her Dr. on Monday morning and see what they say, but I wanted to see if any of you had dealt with this yet? My sister seems to think its her formula, but she has been on Similac Advanced since she was 4 days old and never had an issue until this week!?!
