Sammy has been doing better than we ever could have hoped for. He is aware of Natalie and will approach her and sniff her, but he mostly just keeps his distance and looks on. He whines when she cries and always comes and sits on the foot of the glider while I am rocking her.
She is already way buff. Here she is on her tummy lifting her head.
She is definitely getting bigger- especially in the cheeks and tummy!
