Reasons Eiley is smarter than Heidi:
1. Eiley leaves her clothes and socks on. Heidi takes her clothes and shoes off almost immediately after Tab has wrangled them on.
2. Heidi occasionally pees on the floor. Eiley always uses her diaper.
3. Eiley smiles when we smile or sing or when she's getting changed or bathed (the kid likes to be naked, what can I say?). Heidi smiles at random times. There's no rhyme or reason. She's ridiculous.
4. Heidi can sit and shake hands. Eiley can almost fit her entire fist in her mouth. Okay, maybe this is a point for Heidi.
6. Heidi can barely walk on a leash. Eiley can go for a walk in her stroller perfectly.
7. Heidi sleeps on Tab's head. Eiley sleeps in her own crib.
In conclusion, Eiley is smarter than Heidi. Plus she'll truly know her name soon, where Heidi will probably answer to Tidy.
