Seeger has always been obsessed with trains. I remember when he was 14 months old and he would cry at nap time when I wouldn't let him sleep with his die cast Thomas the Train. (I had visions of him rolling over on it!) His love of Thomas helped him learn his colors and numbers and it has helped him begin to learn to read. I thought his love of everything Thomas might taper off as he got older but its as strong as ever.
