Hey Ladies, this doesn't pertain to daycare necessarily, but want to get your input on this.

My daughter is 3.5, will be 4 in May. She, for some reason, gets overly attached to items, whether it be clothes, toys, etc. If my husband and I mention getting rid of something (whether donating, giving it to someone, or throwing it out) she gets very upset, starts crying and tells us not to get rid of it because she "loves it".
We've tried talking to her about how by donating our stuff we are helping other boys and girls etc., but she still gets upset. If I sell something on kijiji and she sees it going she cries etc. It has gotten to the point where if we are getting rid of something we do it when she is not around because she gets that upset.
We are buying a new car this weekend and when we mentioned getting a new car, she got upset because she loves our current one.
I can't really remember exactly when this all started, but I really don't know how to ease her concerns etc. I mean she got upset because she dropped her napkin on the floor at a restaurant and we gave her a new one. She didn't want the new one because she "loved" her one that dropped on the floor.
Anyone gone through this with their little ones? I'm hoping it's just her age and a stage, but I still find it a little funny that she gets this attached to items.
