Snooping around

So I was snooping around on other blogs comparing the little man's weight to other babies around his age and I realized that my baby is a HOSS! Perfect example is Ebes baby P who was 2 months and 2 weeks and weighed 12 lbs, 6 oz. Husband and I weigh him every Sunday and this last Sunday he weighed in at a whopping 13 lbs, 12 oz. YIKES...that's a full pound and 6 oz more and they were the same birth weight!! Another friend has little T who just isn't that interested in eating so I think my wee man has already passed him up even though T is 5 weeks older. We're still getting up around 3:00 every morning which is hard on me since I now get up at5:00 so I'm going to do some research to see what we can't do to get the little guy sleeping through the nights. I know he can do it b/c he used to sleep through once or twice a week but I think we've had a slight relapse or something b/c it's now a constant thing. Any suggestions??
