I swear my kids can have a growth spurt overnight, or even while they spend the day away from me. Eric was looking much taller the other day when I picked him up, and his shorts seemed a lot looser (more loose?), so I swear he grew a couple of inches at daycare.
Today we went shoe shopping (I should pick a brand of shoes and buy stock in it the way Evan & Eric wear through sneakers), and I was having trouble finding a pair to fit Eric. His last pair was a 6.5, so I thought a 7-7.5 would be the next logical shoe size. I finally took him to the measuring thingy and his big toe was almost touching the 9. We ended up with an 8.5, but seriously--I bought him last pair of shoes three months ago!! Two sizes in three months!! Craziness!!
And yes, I prefer to think my child has feet that magically grew 2 sizes over the past week instead of obsessing about how long he has been running around in too small shoes and maybe that's why he's been such a grump. Also because he has eaten more food in the past 48 hours than the entire week before that ;-)
