I've noticed new schemas being explored lately by Orla and Aidan.
Aidan has been into disconnecting for a long time. However, lately this seems to have lessened, and he's been connecting. Examples include lines of blocks, piano stool tied to the piano, cupboard handles tied together, shoelaces and shoes connected to furniture, and train tracks. On train day, Aidan was really focused on fitting the tracks together and got quite upset when they popped apart (as they often do with this particular set!).
Orla has been rotating, notably herself! She brings helicopter toys to me with glee wherever she finds them, spins wheels on trains, scooters and bicycles with focused attention, and loves to watch the front loader. She is using rotational language (spin, round and round, circle etc).
It will be interesting to watch and see how (and if) these develop further.
