Here are some various things that have become a comfort necessity throughout my pregnancy.
The first is a Mexican Bola charm. I've actually owned one since I was 15! (I had to have one after seeing Brenda from 90210 sporting it with a hippie boho outfit). I wear mine almost every day. I find it reminds me of my connection and relationship to my little one in my belly. The idea is that your baby hears the bell chimes in your tummy, and when he/she is born they recognize the sound and feel comfort.
