Baby stopped liking me

hi,

i feel pathetic writing this but im feeling low about it. My little girl has just turned 7 months and has always looked to me for comfort, smiled/giggled with me the most. All of a sudden it's like she's fallen out of love with me, she avoids eye contact and rarely smiles/babbles at me. Now instead she gets SO excited when she sees daddy who is not a very involved parent at all. It's hurtful as I do EVERYTHING for her. Is she bored of me/doesn't love me? It's been going on for a week now. X
