Our (nearly) 3 YO is supposed to start daycare in a few weeks. He is pretty easy going compared to some children - not too picky or stubborn in most situations. The big issue we have right now though is that he hatesss sharing. My sister and her kiddos just moved down the street so he’s had a lot of cousin time all of the sudden (2 and 4 YOs). He’s not down for them to play with his toys at all. He hoards them and fully loses it if the other kids try to even touch his toys. How do we tackle before daycare starts?
