My little girl babbled up until she was about 4.5 months old. Then she just stopped! She's now a week off 8 months old and still doesn't babble.
The past few days she's started blowing raspberries again but apart from that, nothing!ðŸ˜.
She's definitely not deaf, she looks when you call her name or when she hears noise.
She smiles most of the time and is generally a happy baby. She interacts with you by smiling and laughing, she's just learning to wave and is on and off with it the past few days.
From day one both me and my partner have 'baby talked' to her, we've babbled, we talk to her normal as well (if we're telling her what we're doing etc). We also sing to her all of the time, both nursery rhymes and normal songs.
I'm so worried ðŸ˜
