and now back to the baby

His nicknames so far:

Thee Thee (that would be John)
Teo
Neo (that would be Aidan)
Theo bear
Gerful (he makes a distinct 'gerf' sound when he's grunting)
Snorful (the sound he makes when he has a stuffy nose)
Theodorable

He understands hide and seek (and initiated it with John last night by hiding his face in John's chest and then coming out and looking expectantly until John smiled), is simultaneously amused and bemused by his adoring brothers, goes to sleep when we ask him to (at night), skips naps (during the day) so he doesn't miss anything, and once he's done with an upset, immediately smiles through his tears.
