Baby’s reaction when daddy home

My husband was out of the town for work about 2 weeks,yesterday we went to airport to pick up him, I thought our daughter will be happy to see him but actually she didn’t have any reaction when she see him, then my husband hold her , she was kind of nervous and looking for me.....husband was kind of shocked about that, then maybe one hour later she seems back to before and play with daddy. My husband always feed her and give her bath every night, she seems always happy with daddy too but she didn’t showing emotions yesterday make me a little worried...what do you guys think?
