Ok, so there are some unusual things going on with this growth pattern. As always PLEASE check my math.
Baby weighed in at an entire pound above birth weight at 2 weeks. This is very unusual, because typically a baby looses weight for a few days after being born, usually losing several ounces, then starts gaining about an ounce per day at day 4-6 or so. So 2 weeks weight checks are usually either about where birth weight was, or just a few ounces more, at most about a half pound more. So I wonder if the birth weight or the 2 week weight was off? It only really matters because if this is somehow making doctor assume that 50% is the normal gain rate for your baby, and it is not, he might be comparing percentiles incorrectly. There is nothing inherently "better" about a baby gaining on the 50% over the 25%.
In the 6 weeks (about 42 days) from 2 weeks to 2 months, baby gained 4 pounds 5 ounces - or 69 ounces. So average gain for this period would have been again, an ounce a day- 42 ounces. So baby gained very rapidly during this time, 27 ounces more than average. There is nothing wrong with this, but often when a baby gains very rapidly in the early weeks, baby's normal gain slow down when it happens is more dramatic.
2 months to 3 months - baby gained about a pound over 30 days. So sometime after 2 months, baby started gaining MUCH more slowly than before. Leaving out the first two weeks (that gain was so unusual I have to think there was scale error) baby was...
