well it seems you have a strong bond with your daughter, so you must be doing something right. it seems like your daughter is felling insecure about something,have you asked her why she alwas wants mommy,im a single dad of 2 my daughter is 12 and my son is almost 4 when i send my son to his moms,his mom calls me the next day saying to pick him up becouse he alwas wants dad. i asked my son why dont you want to see mom ,he replied mark hits me .thats my x wifes new boy friend, im not saying thats what your daouters promblum is ,what im saying is sit down and ask her why.

One time someone told me to send something of mine with my son. For about a year (like 10 months or so) I would call him on my break and ask how things are going. I would send my necklace with him and ask him to take care of it until tonight. I would go into his sitter (even when I was late for work)and make sure the transition was smooth let him unload his backpack while I sat there, then kiss him goodbye. Did you talk to her while you two were walking? Did you ask her about her favorite show and what the story might be today? It's hard to say what her fear is .. maybe someone she knows has a sick momma or maybe someone has hurt her feelings or physically, maybe your just her favorite person and she is spoiled to have you at her will. You have to keep talking with her so she understands that her idependence is important to her and to you. Good Luck!
