1st baby is a girl (sorry I don't have a pic on my phone without the hat it was our fb  announcment for my daughter) around 8 weeks she is now 15 months. 
2nd baby at 10 weeks
Do you think maybe number 2 is a boy being baby is situated on the opposite side?
Boy or girl we are happy with either. This is just for fun :0)
