Open Mouth, Insert Foot

Mondays (weather permitting), I take Critter to the public library for a Babies and Books "class". There's usually two dozen kids with their parents or guardians/nannies. I can't say I've befriended any of the parents, just engage in small talk.

Last Monday I saw a woman I hadn't seen in a few weeks (we hadn't gone cause of the snow). We've previously chatted. Her son is almost 2 years old and she's pregnant.

Before the class, I saw her across the room and asked very loudly, loud enough for all to hear, "You're still pregnant?"
"I'm done. I had the baby." She replied.
I was horrified! I just did (said) what I hated done (said) to me! I was so embarrassed. How do I correct this wrong? What do I say to this woman?
"I'm so sorry" I replied. "When did you have the baby?"
Oh, dear goodness!! That wasn't better. Sounded like I'm sorry she had a baby.
H-E-L-P  M-E!!
I wanted to tuck Critter under my arm and make a run for it. I'm such an idiot. I have no social skills. I try to be funny and sometimes it comes out rude or insulting. Many times I'm so not PC. Actually, I don't mind being not PC. I hate political correctness. It always seems to come across phony; Sugar coated phrases not to insult anyone.

I felt really bad. Sure, she still looked pregnant, but did I need to remind her she still has the pudge? I'm sure to many I still look preggo (7 months later). Heck, sometimes I feel like I still have a preggo belly.

"When did you have the baby?" I asked.
"Ten days ago" She replied
"TEN DAYS AGO!" I belted. "Wow, and you're out and about? You're my hero".
Did I just call this woman My Hero? (Wind beneath My Wings)?
The Toddler room the class is held in isn't very big. I felt all eyes were on us as this conversation (me, making an ass out of myself) was going on.
"I had to get out." she politely replied. The class started, she sat across the room from me.

I really feel bad for Critter. I'm probably going to ruin his social life.
