It was talked about on here before and at the time I was on the opposite side of the fence but the more stories I see the more I notice it.
I must say I find Sarah and Jim’s stories with Margot really odd because she is just silent. No babbling or noises in the way you would usually expect a 1 year old to interact with her mum when she is talking to her and her expression is generally blank. Usually when you talk to a toddler they try to communicate back in some way even with eye contact, smiles or screeching, even if they can’t say words yet.
Hopefully in real life she’s babbling away, trying to communicate with them but if not I would hope they have spoken to the health visitor and had her hearing checked just to rule out any issues.
I will say though they if they read this and don’t like it when people mention these thing, they should be considering the way they are choosing to expose their baby to anyone on the Internet. We can only discuss her because you choose to use her as content.
