There's something magical about little kids meeting their baby siblings for the first time. Their love is immediate and guileless; their faces full of wonder. Plus they have no idea how much this tiny new person is going to annoy them someday by repeatedly flicking bits of chewed-up corn across the dinner table, which helps. This adorable big sister is a bit concerned at first, seeing her mom in a hospital bed and asking "What happened?" (Did no one explain??) But once she figures out who that itty bitty human is, there's a whole lot of appreciative squeaking.
