Does my son really need speech therapy? (14 months)

[WillowF]

Saw HV yesterday and she said to put my son down for speech therapy. I am alarmed. Is she right to be concerned? My son started babbling at just over 10 months. He has no words yet. He just points at everything and say "da!" He occasionally says mamamam and bababa but not much else.
Has anyone else's HV says anything less alarmist about a child with no words at 14 months?
I am starting to worry.

My dd's 16 month and doesn't say anything except 'dean' which is the name of her brother and 'ga' for everything else. No mummy or daddy or anything near. I was getting a bit concerned and have been trying my hardest to get her to talk but I can understand what she wants most of the time. I think she's just lazy and will talk when she is good and ready and after reading this thread, I feel reassured and not so worried. You little one will talk when he's ready and I do think it's a bit early for speech therapy.
