Hailey and Jealousy

I have recently introduced Hailey to my friend Zach, it went great until......he gave me a hug goodbye. She threw a huge tantrum and I couldn't figure out why?!?

She loves playing with him, he sits there and makes voices, and tickles her, carries her, and does everything and she loves it! Mommy is nothing when Zach is around! She even loves when he teaches her naughty tricks, and Mommy get's upset. They both laugh.


The laughing stop's though, the moment he decides to give me any attention that takes away from her, which could mean talking to, or laughing with Mommy, or hugging Mommy. She is showing signs of major jealousy, or she has a cute little crush :-)
