We took a short hike up the mountain near our house this morning. Anna wanted to walk so we just went 1km and turned around. I think she could have handled more but we didn't want to push it. When we got home she said, "my shoes are tired." Sarah didn't take a nap so she wasn't excited about the hike (she was fine as long as Craig kept moving) but she seemed to like the backpack carrier relatively well. I'll have to try her in it when Anna is in school sometime.
