my baby is 11 weeks old and for the past week or so has been waking consistently at the 4 or 4:30 hour wanting his pacifier. he doesn't usually want to eat until closer to the 6:30 hour, but he will wake at 4:30 am and every 45 minutes from there on out needing his pacifier. he has a DF at 11 and then sleeps soundly until 4:30 and then is up. any idesa?
