What happens if my baby is small for dates?
Babies are sometimes called small for gestational age (SGA) or small for dates (SFD). Most babies that are smaller than expected will be healthy. But up to 10% of pregnancies will be affected by FGR and will need close monitoring during pregnancy. In some cases, you may need to give birth earlier than expected.

In fact, if catch-up is to occur, it general occurs rapidly within the first 3 to 6 months after birth, and will typically be complete before 2 years of age.
What happens if baby is measuring small at 37 weeks?
Babies are diagnosed with intrauterine growth restriction (IUGR) if they appear to be smaller than expected.

How can I increase fetal growth?
An increased intake of fruits and vegetables or vitamin C at mid-pregnancy is associated with increased fetal growth and infant growth up to 6 months of age.
What are the symptoms that baby is not growing in womb?
But a baby with FGR may have certain signs after birth, such as:
- Low birth weight.
- Low blood sugar levels.
- Lower body temperature.
- High level of red blood cells.
- Trouble fighting infections.
What causes a fetus to stop growing in the third trimester?
Often, IUGR happens because the fetus doesn’t get enough nutrients and nourishment. This can happen if there is a problem with: the placenta, the tissue that brings nutrients and oxygen to the developing baby. the blood flow in the umbilical cord, which connects the baby to the placenta.
Why do they induce small babies early?
