I have a 15 month old baby girl. I am with my daughter 24/7 and I am basically her security blanket. However, for the past 4 days now she has not wanted me at all. She will only her grandmother or her grandfather. I'm sure this is just a stage, but it hurts. My question is why is she going through this stage and how long will last? She also hits me and then kisses me. I just tell her we do not hit, we love. Hope you can give me answer to my questions.
