DS2 will be 2 in 2 months, and the only consonant sounds he can make are 'n', 'm', 'd', 'j' and 'b' - (so he can say 'no', 'mummy', 'daddy' 'baw' (for ball), 'doh' (for dog), and 'joo' (for juice). And those are pretty much the only words he can say - he's never attempted his name, which starts with 'c', or seemed able to sound out any of the other consonants. I am just wondering if I should see the HV about this?
