DS is going to dds daycare for Christmas break. I love it, it's a great place - it's actually a private school that has a daycare too so it is big and awesome and ds doesn't feel like he is in "daycare".
So today...
DD was sitting on her teachers lap in the gym. And her teacher told me that when DSs class walked into the gym, he came up to her, pointed at DD and said "she's mine".
Her teacher was like "I know" and ds said "good".
And the he kept checking on her throughout rec time. Lol.
