I wondered the same. We expected Suri to get to 4-4 1/2 pounds ... Which is really small to me! But she just turned 6 months old and she is 1 pound 14 ounces! She has grown since we got her but not very much. We got her at 8 weeks old and she was 1 pound 9 ounces? I think it's weird but the vet knew she would be small because she is small structuarally. So I guess we will see what she thinks at her next appointment.
