I don't know if this is just regular toddler behaviour or what, but LO has this thing with possession. For instance, certain mugs will be used by DH and LO will keep saying "baba's tea" if i use his. When we go to a party and the host takes our coats, she will flip out because she thinks he is taking them away. I have to take her to where the coats are just to reassure her that they aren't going anywhere. She does this with menus at restaurants too. She gets upset if someone else is using something that's ours.

Is this normal? It's not just her getting mad if people use her things (she's getting better at that) but if in general other people are using things don't belong to them. I sometimes worry it's the beginning of OCD!
