C's New Sweater for the Fall (and Spring)

I have been working on this sweater for Lil C for several months now. It's finally done! I got the pattern from Vintage Baby Knits and loved the diamond details in it.

I love the yarn i used (this taupe colour is my favourite colour these days) but i don't know what happened to my size. I swear i tested my gauge, but the sweater is clearly bigger than the 18 - 24 months size i chose. I guess that's a good thing as i just finished it and it's now Fall and C is 26 months!
The biggest part that i had to alter was the neckline. It was a boatneck but looked more like an 'off the shoulder look' on C that i knew it would annoy us both. I found a tutorial for 'elastic casting off' on-line and it really not only completed the look, it saved the sweater!
