It takes time amiga due to so many things different and unfamiliar. Pia has been out about 3 times on her own - twice when I was out. I am amazed and a little worried about some of the places where she ended up going. I have been here in Leeds for almost 5 years and never knew there was a fishmarket in the city centre.
I suggest going for regular walks with hubby and baby. Then when you are ready you will venture out without him to the places you are familiar with and then, eventulally further afield.
Good luck!
