My 9m old isn’t babbling yet - no bababa/dadadad etc. she’s not silent by any means, she squeals (with happiness and upset), coos and makes noises but I just wouldn’t describe any of them as babbling. She’s not my first and my first two babies were definitely babbling by this age so I’m a bit anxious. How unusual is this? The health visitor asq suggests 3 words by this point as well which we definitely definitely don’t have. (All other areas she seems to be on track and very similar to my first two).
