The actual age of the baby is twelve weeks behind the age you measure after birth. So physical development is normal.For mental development, there is relaxation up to two years of age for preterm. You can consult a local pediatrician for that. There are chances as in the general population for a chance of preterm in the next pregnancy.Hope I have answered your query. Let me know if I can assist you further.Regards,Dr. Susheel Kumar Saini </s>
