My babies are measuring on the smaller side despite all the weight I have put on. I am trying to increase protein this time around before my next ultrasound to see if they get a bit bigger. Want twins to be as big as possible as early as possible to avoid preterm birth and low birth weight. Did anyone try this and it was helpful? Any tricks or snacks you used? I am trying to drink 2 premier protein shakes a day which each have 30g of protein and also got a protein bar to eat each day. I also have Greek yogurt, spinach, and some sort of meat in my day.
