Milestone moment

Brendan slept last night without Tee, his blankie. He's slept with Tee every night since before he was a year old. For about 2.5 years he slept with Tee and Dorothy the dinosaur. Then in May he added a Tyrone from the Backyardigans that I got him in Minneapolis and a little teddy bear from a Happy Meal. Then a monkey from Old Navy and recently a blue bear from the carnival. He had a regular menagerie with him. But gradually he'd been throwing some of the menagerie out of his bed, sometimes even chucking them down the stairs before bedtime. But he still was deeply in love with Tee. But last night he went to put himself to bed again, which has been going on now almost a week and that I still find weird. He took his Jessie doll with him and when I went to hand him Tee and his blue bear that had been sitting on the steps he told me he didn't want them. I brought them into his room and anyway and he yelled and threw Tee down the stairs. I knew he'd be back out for Tee before he fell asleep, but it never happened. When I got him up this morning, he clutched his beloved new Jessie doll from Toy Story (although I wonder how beloved she'll remain after Buzz and Woody arrive as I expect them to today) but never said a word about Tee. I'm not ready for my baby to give up his blankie. He's only 4!!!!!
