Between 7&8 months? If my scale is accurate which I've used it each time so it's got to be relative, he has only gained 4oz. Should I be concerned about this? It's very possible that he grew length wise and took up all of his weight gain doing that? I don't have a measure tape on me to check. Even still that seems like VERY little weight gain, he looks lean but not unhealthy by any means, he's also SUPER active. Curious how much talks babes gained in the last month?? And if I should contact his ped about it? I'm a FTM so not sure how these things typically go haha pic because we just took it today and he turned 8 mos yesterday
