Who has how many babies weigh at 2 months? We already have about 6 kg. Growth is 59. We're completely on breastfeeding. Everyone says that I fed her too much. They say we don't look like 2 months old, but like all 4. To the doctor now only in 3.5 months, because she's on vacation. I feed her by demand. Since we can't stand 3 hours. And every two hours we eat at night.
