Ha, I was 30 when I got pregnant and felt just like a clueless 15 year old who had just fallen off the turnip truck. I had no experience with growing babies.
What I did not do was read the "what to expect when you are expecting" book. My hospital gave me one, but I remembered when my girlfriend read it and then automatically thought she had all the bad things happening to her. LOL So I skipped that one. I think my son's father read more of it than I did.
I looked to my doctor for advice, listened to my body, and just took it week by week. When I had a question, I asked my doctor. I didn't listen to the other ladies in the check out line telling me horror stories. I did take child birth classes so I knew what to expect and did talk to the hospital to know what to expect there when I went into labor.
I actually had a wonderful pregnancy - stress free and tripping through the tulips in my uniformed bliss.
My best advice would be to take it slow - it is a huge thing to sink in. Don't project and start to worry about things that are going to happen way down the line - like schools, and prom, and college. Do ask questions when you have them, do eat a balanced diet but let yourself give into cravings (they are odd and quirky things - I actually ate and enjoyed brussel sprouts when pregnant!!) Ignore the horror stories - we women are so weird about weirding each other out about pregnancy sometimes. LOL
Most of all, enjoy this time. It's fun and exciting and a little scary and overwhelming at times - but gosh, there is nothing more fun than buying itsy, bitsy baby booties knowing that soon you will have a beautiful child to wear them.
Congratulations on your pregnancy - Enjoy it and have fun!!!!
God Bless
