Trixie has taken more of a shine to Bailey lately -- I was in the kitchen doing something while Bailey was in his bouncy chair in the next room and I heard Trixie say "Peek-a-boo, Bailey! Peek-a-boo" so I looked around, and sure enough, she was playing pee-a-boo with him. She kisses him good-bye when I drop him off (down the hall from her) at daycare, and this morning she insisted that he sit next to her on the couch, so she could show him how to kick his legs.
Bailey started full time in daycare this week, which means dropping off (or picking up) two at once. This is a challenge for the solo parent doing the dropping off or picking up, since Bailey goes in the Kelty front-loader and Trixie is asked to walk with us, and she often wants to be carried by said parent. But she has thus far risen nicely to the challenge. I am no doubt jinxing it merely by saying so.
We aren't taking a stroller because a) they take up incredible amounts of space on the subway during rush hour and b) Trixie has legs and c) she's only being asked to walk a total of four blocks, two on each end of the trip, so it's not like she's tired.
