Congrats! what a special time!
It sounds like foot in mouth disease is contagious! I had a similar situation when I first found out I was pregnant. I had been told due to medical complications (me) that the chance of me having children would be next to nothing. Meanwhile SIL is pregnant and doesnt tell anyone until she is almost 7 months along (long story about how she was going to tell everyone the baby was premature....at almost 9 pounds......but that is another story). MIL was upset because her daughter didn't tell her she was pregnant and "wanted to go thru this with her children". A few months later I started showing symptoms of pregnancy, which was confirmed. I excitedly tell family and my family was wonderful! when we tell his family, I get "great, now that is all we will hear about for the next 9 months". So, I kind of did not want to share anything with them. They got a "fine" if asked how I was feeling, where my family wanted to know everything.
I agree with PP that nobody knows what they are doing! If you have ever watched "Friends" when Rachel was having her baby shower, she looked at the breast pump and said "Is this a beer bong for a baby?" .......it's trial and error and just let your physician guide you thru the pregnancy, let your baby guide you (you'll come to know their different cries). You'll do great!
