Brother and sisterly love

My two little ones adore each other and it is really heartwarming to see how Laetitia is caring towards her little brother. She is always asking to give hugs and kisses or to carry him in her arms. Most of the time it's all quite harmless except for the rare occasion when she tries to lift him up to carry him in her arms all by herself. Well, Loïc is about half her weight so not only is it difficult for her to lift him up but also dangerous should she drop him due to her lack of strength. However, aside from that, I usually am able to leave them together in the room for a short time while keeping my ears and eyes open. Loïc's face would also light up when his sister is around.
