Is it normal for a pediatrician to constantly question a babies size? I don't know if any one remembers but my son had some growth issues early on. His lowest after birth weight was 6.4lbs around 1 week old and now at 4 months he's 11.1lbs. He's also gotten 4 inches taller and his head has grown too. He is constantly growing at this point and has been for a few months but he's only in the 1% on the growth charts. I think he is doing just fine but his pediatrician is still questioning why he's not bigger. I allowed him to take blood this last well check to test for metabolic issues and iron levels which all came back normal. At this point I feel like my son has proven he's perfectly healthy and I'm not concerned at all. Pediatrician however still wants him to do weight checks. Is this a normal experience for breastfed babies because I never had my pediatricians question my other two formula fed babies half this much.
