Osian's new cheeky expression has become such a regular thing I just had to have a post somewhere on here about it. Although he does it so often I haven't managed to get many photos. When he scrunches up his nose he either does a really cheeky little laugh or just breathes in and out very fast and gets so excited.
I'm don't think he's picked this up from anywhere, it just seems be something he's learnt to do all on his own. Even though this little face is definitely becoming an ordinary moment I don't think it will ever get 'old' it makes everyone smile/laugh as much as the first time he did it.
