Oh spring that is absolutely fantastic that you had such a lovely ob appt. What fantastic news that you and your little one are travelling along so nicely. We always have a few babies born on Christmas day at work and it is really special. Last Christmas I was a midwife for 3 different births - boy did I run that shift but they were all beautiful births.
Don't worry about the size of bubby. I think bigger babies are easier because they help. DS was 4400gm and was easier than DD who was 3850gm.
You are going to do the most amazing job giving birth to your little one. I can't wait to see your BA. I'm going to go out on a limb and pick a NYE babe for you, just before midnight. Last BB baby of the year.
