new words keep coming

So Soeun just got back from a few days away and I was excited to get out the cucumber so he could hear the toddlers word for it, it doesn't sound exactly right but he has a word for it. I didn't realise but Soeun hadn't heard him say shoes before, he has been saying it to me a lot over the last few days so I didn't realise it was a new word. And now when he gets out of the bath he knows to ask for a towel, or something that sounds like a towel.
