Doctor's appt. and 1 month left

We had a doctor's appt/sonogram at 11:15 this morning. Tristan is still doing really good. His heart rate was 142, he has gained another 1/2 lb., so he now weighs 4 lbs. 3 oz., and all of his measurements are still right where they should be except his stomach is measuring 4 weeks behind (it's only been 2 weeks behind up until today). But the exciting thing today is that there is still the same amount of fluid behind his head, what an answer to prayer, there has been no increase in 2 weeks! The doctor's only real concern today is that I am measuring 3 weeks ahead, I have always measured 2 weeks but it seems to be increasing, obviously the concern is that I could go into labor early. Besides that, overall our doctor is still very impressed with Tristan's progression, as we have been told that a lot of Trisomy 18 babies degress or stop growing by the 7th month. It is so hard to believe that we only have 1 month from today until Tristan is born. When you first find out you're pregnant it's as though the first few weeks seem to go by so slow, yet here we are with only one month left. We are still so excited because we are longing to hold Tristan and see the baby we have so earnestly prayed for every day and yet we also realize we are, in a way, almost at the end of our journey and that we may not have long with Tristan, that's when I wish THIS pregnancy wouldn't end. Please continue to pray for us during this last month that my fluid will not increase so that I DO NOT go into labor early, that we will still feel a peace about Tristan's life, no matter how long or short, that Tristan will continue to grow and gain weight and that he will have the strength to hang on just one more month!
