I love to observe the interaction between those 2:
- There is often competition for toys that results in crying from one of both (of both of them).
- Kabouter loves to "supervise" his little brother and tell him and us what he's not supposed to do, ...
- Beertje wants to copy and join in on anything Kabouter is doing
- They can hug each other spontaneously
- They can sit and giggle together in a way that it's contagious for all of us
