Just wondering how big your babies were at birth and how big they were at 8 weeks. My son is 8 weeks and was 7.11 at birth, he did not fit into newborn clothes as his feet were to big. Now at 8 weeks he fits into 3-6mth clothing perfectly and weighs 12.9 and a half. Just wondering if anyone elses babys have put this much weight on as rapidly as straight after birth he dropped to 6.15.
