I personally felt it was very important to wake up my son at this age to ensure he got a good start at breastfeeding. Unless, your pediatrician was also a nursing mother at one point, I would not follow their advice. You don't mention whether he was a smaller or larger baby, but being birth weight at the two weeks is considered okay, BUT I would still make sure that you wake him up every 2 hours during the day and only let him go for one 4 or 5 hour stretch at nite until you're certain he's thriving. If there is a potential problem, you can easily avoid it by following this approach. If you wait two more weeks, it will be much harder. I followed this approach with my second son until he was two months and was gaining great. This was because of extreme difficulties with my first who was just 2 ounces below birth weight at the two week and still hadn't gained at the 4 week. It was very hard to build my milk supply at that point as it was necessary to supplement with formula.
