"Are you going to have a Baaaby?"

Alright so last week it kind of hit me, this belly of mine is growing and I look pregnant. I've known this for weeks, but last week is when it became apparent that people who may not know me or who I haven't told that I'm pregnant, can now tell just by looking. The way I'm carrying is what I would call "high and round", and not straight out. I can still do up most of my regular pants but my slimmer jeans are uncomfortable and I even wore maternity pants for the first time on Saturday, man there is no hiding anything in those! Here is how I came to this realization . . .
With the new job I have as a teacher in an after school program with Elementary kids, we have to wear these red polos. The only size they had left was S and 2X. I honestly would've taken the 2X but it would've looked ridiculous and the S is ok, I guess. It's not like I'm trying to hide my belly but when I was hired I hadn't told anyone outright that I was pregnant. Last week, three weeks into this job, these first graders started coming up to me and just rubbing my belly? That was a little weird. Then this 3rd grade girl, who isn't even part of the program, spotted me across the playground. She made eye contact with me and smiled great big. She didn't take her eyes off me, or the smile off her cute round face as she slowly stopped her swing, got off, walked towards me and asked "Are you going to have a Baaaby?" I told her yes. She then asked "Can I touch your belly?" I said no, but thanks for asking first. She was still talking to me when some of the other teachers walked up. So I told them too. Two of the ladies were like "oh, I was kind of wondering" and the other one was like "no way! I had no idea". Yesterday I saw our boss so I pulled her aside and told her because I didn't want her to hear it from one of the kids or someone else first. She also was like, "I had no idea!". Those polos can be deceiving I suppose, but wearing anything else, there is no more hiding this belly of mine, and I can't even recognize my own belly button anymore!
Sorry for three different pictures, we were trying to get the best one. (Please note the table setting in the background of the 3rd, the first time I've used my china since we've moved!)
I'm 25 weeks or 5.5 months pregnant. 3rd trimester starts December 2nd! Wow, so much to do!
