This is really odd and something I haven't encountered before - has anyone else's child done it?
Ds2 is just over 2, and has quite a few littlewords now - but the way he learns them is weird.
He'll start off with the last consonant - like if it's 'milk' he'll call it 'k' (as in phonics, so literally just the 'k' sound)
then gradulally it'll progress to 'ilk' then finally 'morky'
but he does get there.
We often have entire sentences composed of phonic consonants!!
'Mummy where's k? t s mummy! T S!!!!'
No idea what that sentence means btw
