[series of photos with Mattias and Trixie playing ball removed]
However, three years ago, when I kept a 4 year-old Noah at home with me for half days, I noticed how Noah and Mattias's (then 16 months +) relationship blossomed. To this day, they still genuinely enjoy each other's company and play together really well, despite the 3 year age difference. I'm hoping this will repeat with Trixie and Mattias. I know Mattias and Trixie will ultimately have a different relationship than Mattias and Noah. But it's such a gift to have a sibling who is also a friend.
