hi Dr, I had a preterm delivery at 28 weeks due to low placenta position and twin pregnancy as well. one of the twins survived after staying at hospital for 1,5 mnths, he is now 9 mnths-3 (according to the due date delivery).my 1st. question regarding my pre term baby, does this will cause him any mental delay in recognition? i notice that his physical development is delayed the 3 mnths difference, how can i notice his mental development? my 2nd. question, what is the probability of the pre term again in case of single pregnancy?is there any precautions to be taken? thnx alot
