Here are some recent examples of "being brudders":
One afternoon Tommy woke up from nap much earlier than Ben. We fixed three snacks (one for me, one for Tommy, one for Ben) and then ate our two snacks. When Ben woke up about thirty minutes later, Tommy brought his snack and his water cup to him in bed. Then Ben shared some of his snack with Tommy. Awwww....
"Being brudders" - the boys have a game where one will lay on the other's lap and they say they're "being brothers". After a few minutes, this usually turns into one of two games: pretending to be a baby, complete with pretend crying and pretend tantrums, or a full-on wrestling match. But it's incredibly heartwarming while it lasts.
Tommy "reading" a book to Ben. The cuteness occurring here was at such high levels that we had to take a video of it to capture the moment.
