Growth Spurt?

I swear she outgrew these sandals overnight. She wore them about 4 days ago and they fit fine...and then yesterday I noticed her toes hanging off the edge! I bought these sandals only about 2 months ago in a size larger than the one she was wearing at the time. I was warned that this might happen- growing through an entire shoe size in only a matter of weeks! This also explains why she's been desperate to pull her regular shoes off all the time-too small and I didn't even know! So much for the cute summer shoes she already has, I guess I'll have to start over. And in case anyone is interested, or sees a pair of adorable toddler shoes they can't resist...this now puts her in size 6. :)
