Worried about my daughters development

[Mum2ElmoFan]

Hey all FTM MUM here
My daughter is 15 months old on the 1st of March she doesn't point doesn't wave doesn't copy me
She does respond to her name
Great eye contact
And will bring you things when you say ta
She says mama and dada but not to me specially
The fact she's still not waving after her development review really has me concerned

Does anyone have any advice
Pls
