Thanks all that really helped. I'm sure I started to feel little flutters at about 15 weeks and over the past week or so I have started to feel little kicks mainly in the evening.
My daughter is 5 1/2 now and will be almost 6 when baby is born. I think we will find out what we are having as I'm an impatient person and also for Gracie as she seems to be convinced that it's a boy and I don't want her to be funny about it if we bring a girl home, just to prepare he and tell how exciting it will be to have a sister.
