DS is 14 months. This is pretty petty and could be meaningless but something the HV said has stuck in my head and I'm wondering if there's any truth in it or if it's utter crap. 
In May DS had his 1 year check. The HV was happy with him, told me to keep an eye on his "talking" and that by 14 months he should be putting together 2-3 word sentences and to watch for delayed speech. Is that true?
DS spends most of his time chatting away, but I've no idea what he's saying. He says 'Dada', and 'no' but only after I've said it - so repeating what I say. He's been walking since April, he waves, high fives, kisses etc. so I've never felt there's an issue but the comment about his speech won't leave my conscious.
