So my daughter doesn't talk and she's 20 months old the only thing she does say is "mama" but she doesn't know she's calling for me.. in other words she doesn't know Mama means mummy.

I'm going gp with her but I'm just sooo worried and just keep thinking the worse.. today the manger at the nursery said there's something wrong with her as they have done tests on her today.. she doesn't point she says nothing.. we call her by her name sometimes and she doesn't look.. she doesn't really like to play, she loves to shout. she understand no.. she hits her head on the floor when she's angry and something wired which she does is when we put her on her high chair or a shopping trolley she tenses her self so her legs are all straight and she sweats when she does it and gets red I tell her "stop" but it like she can't hear me and keeps doing it (it's soo wired)
