Sometimes they are in a sweet spot, long stretches where there's just sweetness. He asking her to read to him, pulling her hand to take her in their room, wanting her to do something with him over anyone else. She being so attentive to his needs, offering to read a digger book, turning his five minute show on over and over again, getting a pillow and blanket to snuggle together.
Makes me wonder if, at this young age, there were sweet spots between my brother and I. I remember lots and lots of years of bickering, taunting him by crossing the invisible line in the backseat of the car, my mom warning me he'd be bigger than me one day (in case you don't know him, he's got ten inches on me), and then becoming friends as adults.
How do you make sure they stay friends? How do you make sure they know that friends come and go but siblings are yours forever?
