You should defintly giver her times outs during the day, prefferably at nap time, and maybe even for a hour or more. It is actually for the better of her mental strength when she gets older for the times when you cant possibly be around her. It also teaches her that you will always come back. Let her cry if need, give her plenty of toys be but dont go back in the room to sooth her, she needs to get the hang of it. I used to drop Rory off at my mom's for a couple of hours too so when we go outta town she will already know her grandma and now she knows it as her second home. Rory had started to be so bad that if I left the room for a second she would cry....even if there was someone else in the room! It might seem flattering to have such a loyal loving companion but the attachement can cause extreme anxiety which could develop into bigger issues. If you had to leave her over night at a vet (god forbid) if she ever got hurt or ran astray, you would want her to feel comfertable in her surroundings so as not to highten the scary situation!
