Aww hun give her time. She is still a baby. She loves you and that love will grow the longer she is with you.
My baby ziggy loves his granny and I use to be a lil jealous BUT he knows who mommy is and will chose me above anyone else. He is now 2 uears old and shows his love all the time. As we speak he is on my lap asleep and his granny is sitting next to us...
Give her time
