It doesn't hurt to get an opinion from a Speech Pathologist.

Both my boys are delayed. Brendan has been in therapy since 11 months and Tristan started this month (9 months old) Brendan started for feeding issues and went on to the speech side of things. Tristan is in it for the speech side of things as he is not babbling at all. The earlier you get onto the delay the better the outcome.

Our CHN referred the boys onto the speech therapist.

I've got some material that might be of some help to you if you want I can PM it to you. It's some handouts that I was given during Brendan's Speech Group Session.
