Five things which suggest that my toddler may be a Time Lord:
1. He has an affinity for robot dogs.
2. He's rarely called by his given name, but most often by an accepted generic appellation: (The Doctor/ The Baby).
3. He loves bananas.
4. He's usually either inside of, headed for, or talking about his box. (Mind you, J's is a sandbox...)
5. When he sees something new, unusual, or especially dangerous, his instinct is to run toward it. Gleefully.

ETA: Ha. And given that my baby-making days are behind me for good, I guess he is also the last of his kind. ;)
