I wouldn't be worried. My eldest didn't get her first teeth until a fortnight before her 1st birthday. The babbling/noises all seem normal to me too. Actually you've reminded me that I need to 'high-five' my 9 month old- we haven't even done that yet! There's no dada/mama noises here either but plenty of other noises.
Babbling can start anytime after 6 months and upto 9 months, so you still got time.
My LO was babbling at 6.5 months, but at 8-9 months, he did know his name or hi-fi like your daughter, so she seems to be doing good
Gracie wasn't really a banker either. She's 17 months now and has quite a few words (maybe 20-30) and can count to three, but she has a fantastic understanding of things for her age - I was really worried as she was always on the later side for social development but now she seems to be quite advanced for her age. I don't think Gracie ever babbled to be honest, she did the shrieking type noises you mentioned. I think she is just an observer and waits u til she develops a skill fully before using it. She's like a sponge now, but until she actually showed the skills I was really worried (I posted here lots?
The teeth thing is nothing to worry about either, Gracie was a really early teether and I was worried about how early she was. Looks like your son was also pretty early so that might make her seem more late if that makes sense?
2 of mine didn't have a single tooth til 13 months! Nothing to worry about in fact I was told the later the better, I wouldn't be concerned about no babbling either so long as she's making noises, she's still just a baby and a very cute one at that!
