Second words

So Miles's mum points out that his first word was "mum". True indeed, even if he has little idea just yet what the babbling sounds he makes actually mean (sorry Mum). If I'm wrong, and he uttered "mum" to express his love and affection for his number one carer and fan, then what's he trying to tell us the rest of the time?

When he's not nattering on about "mumumumumumum", he's mostly giving it staccato bursts of "mmmbop ... mmmbop ... mmmmmmmbop". Which can only mean that there's a certain mid 90s boy band that he wants added to his music collection. I'll get that arranged shortly so that hopefully we can emulate his idols and turn Miles into a lucrative child star ASAP.
