At the tender age of 3-1/2 months, Benjamin Brady can check flying internationally off his to-do list. He was spotted with mom Gisele Bundchen on Monday at LAX en route to Bundchen’s native Brazil. She sure is getting her money’s worth out of that ERGO organic baby carrier, which apparently is her favorite mode of transport for the little guy. And it looks like the “plaid is the new black” trend among celebrity moms is still in. Another photo after the jump.
