How much have they grown?

Here are two photos - the left one taken in August 2010, when the boys had just arrived home: they sleep inside the triplet-pram. The other photo is taken on last Sunday (20 November 2011), when, out of curiousity, I wanted to try if they still fit to the triplet-pram and if we could take a ride with it. But as you see - it was too tight for them!
Yes, I do not have babies at home anymore... I have 3 little men... :)
