To long between feedings :(

G
The last 3 nights there have been about 5 hours between feedings. My son is almost 2 weeks and we just got back to a weight the doctor is okay with but still not birthweight.  I have alarms set for every 3 hours, but I sleep through them, he wakes me up but he didn't cry or anything the past few nights. I feel awful because it's now the third night he's gone to long. 😞
