Baby measuring small?

Kristina

Anyone else get told their baby is measuring on the small side? This is my 4th baby, little girl, and this is a first for me. I went in today at 26 weeks and 6 days and she told me my baby girl is in the 21st percentile for weight. She weighs 1lb 10oz. She wants to keep a close eye on her and was concerned. Is that weight small for a 27 Weeker?
