Training a Puppy That Is Afraid of Me?

I recently bought my puppy and she is scared of me, but I'm trying to house train her. She loves being outside and she will play with me outside, but I still can't move towards her. Inside she just sits in a corner. I want to walk her on a leash. I've got a 12 month old baby. Any suggestions on how I can house train her with my baby? My baby is busy; he likes to explore and move around so it makes it hard to house train properly. I need help with any advice on traing and everything including walking, sitting, stopping, going, etc. with my command and making her feel at home.
