I understand that this is probably a survival thing for a younger sibling but he sure has been saying it a lot lately.
Milan is usually stellar at sharing with Julien and he is pretty good at taking turns. But Julien's stuff has mostly consisted of hand-me-downs, which makes me think that he probably knew that he had to wait for things since everything around him belonged to someone else first. This suddenly changed last night when we caved and bought him a toy car. Now his new thing will have to be learning how to share something that belongs to him with others. Good practice, I guess, for when a new little one joins our family.
