This seems to be a favorite activity in Erik's room. Hanging on/leaning over/chewing on the "pen" walls. Their room is designed to have a "big" area with linoleum that is open and unobstructed. Lena sits in a stroller along one wall, the TV is in the center of the same wall, and Dima sits in a plastic chair or stands in a standing table along a "pen". It's like a huge playpen. There is a swing and a ballpit in there, that never seem to be used, ever. The kids mostly lie on the padded floor or hang out on the railing. I wonder how much paint Erik has injested in his 5 years there?? There are very few "loose" toys in the "pen", and precious little to do. We did one day see the caregivers have Denis and Erik in a walker and let them walk around on the linoleum, which was great, but I think that is a rarity. I wonder how Erik will like his bedroom with all of the cabinets and drawers full of toys to explore and the freedom to come and go as he pleases?? :o)
