I gave birth August 15, Monday. At the hospital she latched perfectly fine and wasn't having any problems whatsoever the day and a half I was there. Now that we are home...she doesn't latch. She doesn't even try. She sleeps and wakes up, she's content and not fussy but the last time she ate today was 4am this morning, it's now 2pm and she's not latched. anyone ever have a baby that didn't want to eat? I just hop nothing is wrong with her. She has an appointment with her pediatrician tomorrow at 4pm I figured if she's hungry she will let me know in the mean time
