Per the title, my daughter only really says Mama. I haven't been worried until now - she has been more focused on walking, and other physical things, but she's getting to the point where it seems she's unusually late in talking.
She understands well - she will point to a variety of different things her her picture books when I ask her. She hands me things when asked. She claps on command - that sort of thing.
She's also developed various other ways of communicating with sound and signs. She will smack her lips pointedly when she's hungry. She does a specific "dance move" with her hands when she wants us to play music. She can shake her head for "no" (and usually does this when I ask her to try and say things!).
She does babble and can make a variety of consonant sounds but I wouldn't describe her as talkative and she'll often fall back on "oooh" cooing at varying tones to express interest/pleasure/anger. She'll intermittently produce multisyllable nonsense words. I THINK she's trying to copy sounds from words - like she'll sometimes go "puh puh puh" if I'm talking about her Panda, but it's not quite consistent enough that I'm sure it's not coincidence.
I keep seeing different guidelines about what is or isn't normal at 15/16/18 months, and I'm looking for some more experienced parents' experiences on whether this is okay?
