We took the twins for their 15 month checkup yesterday - it may just be me but time sure does fly when the kids are young!
Charlie is 30 pounds and Scarlett is up to 24 pounds. They are both within the scale of where they should be - Charlie is naturally up near the top, I blame that on the fact that he steals a lot of his sisters food!
They are now walking and babbling a lot but no real words. They do say "ut-oh" but we don't think they know what it means - the just think it's funny to say when they drop their milk cups off their high chairs.
A video of the twins walking around - sorry about the orientation, I didn't have time to reshoot or to edit it.
