Mavis is 5 weeks old today and it shows. She notices colorful objects, rattles & lights now. She LOVES music of all kinds, from mom's bad singing to bluegrass to loud distorted rock. She can hold that heavy head up for longer periods and is getting better control over her arms. She talks to herself more & has very distinct (& loud) cries for anger and frustration. I guess you'd say she's all grown up.
