Baby tummy?

I have to tell you a story that happened to me last week at work. There is a student that I have gotten to know very well. He is a little boy with downs syndrome. I have known, (we will call him M,) M for three years now. Every morning M sees me, gets a big smile on his face and says, "Mrs. V.," and then gives me a hug. Well, the same thing happened last Friday. Except, this time with his head hitting right at my belly he looked up at me and said, "baby tummy?" Keep in mind that I haven't said anything to the kids at school yet. I guess you could say I am protecting myself for the "what-ifs." After M did this I smiled and nodded. Then he proceeded to try to lift up my shirt and see it. As I laughed and told him he could see it just fine through my shirt, I couldn't help but to feel as if I was overflowing with joy.
I had a Dr. apt last week. I had to see the nurse practitioner because my Dr. was out on an emergency c-section. I would have preferred to see my Dr, oh well. Everything was fine. I heard the heartbeat. In fact the NP commented on how active the baby was. She would get the heartbeat and then a second later she would lose it and it would be in a completely different place. I had to laugh at that. Now, I don't have an apt. until Oct. 14. That is actually our 20 wk. ultrasound. I'm excited for the next apt., but also not wanting to wait so long in between apts. I asked the NP if I could bump up the apt. a week or two. She said no. I thought about still calling and asking my Dr., but I decided that I need to wait. God has been teaching me so much about waiting and relying on Him in the mean time and I think that is what I am suppose to do.
Still sitting and waiting to feel my baby move. Everyone keeps asking me if I can feel the baby yet. I've been praying for that to happen sooner than later.
My brother and his wife are due in less than a month. I am so excited to hold that child of theirs that they have been dreaming of and praying and preparing for quite awhile now.
