I am getting really upset and super bummed out - here's my situation:

My daughters father & I are no longer together. Our daughter is [almost] 8 months old. For the first 5 months of her life, she was always with me besides for when I went to work, she would then go with her grandma (his mom), and I would pick her up right after work. Her father and I had went in front of a mediator & he was granted some custody. We didn't go by their agreement, we made up our own. Anyway. My daughter goes with her dad every other weekend and every Wednesday. He lives with his mom and my daughter goes over to their place while I'm at work everyday for 8hrs (he also works same time if weather is good). 

Lately, I feel as though my daughter doesn't know I'm her mom. I feel like she spends way more time over there although I have primary physical custody. I feel like she may think her grandmother is her mother. I feel like my daughter may think I'm the baby sitter. How can I tell? What do I do? Anyone else going through or has gone through this?
