I am worried about our 19 month old son and his behaviour with others. At home he's a usual toddler, gets stroppy if we dont do things he wants immediately although he can't talk yet so it's not easy figuring out what that is all the time. He has the odd tantrum too but that's normal and I can handle that. What I think is strange and worrying me a lot is how he acts with other people. He gets really hysterical and cries a lot at people who he doesn't know and people he does know. If we go out for a walk he will point at a dog but if the dog owner smiles at him he will scream. If my neighbour talks to me he will scream and cry. He hates going to the sure start groups but I have been trying to take him weekly for a few months to get him used to that environment with other children and adults but this morning he just got absolutely hysterical and I ended up bursting into tears too which is embarrassing and then I had to leave as he was upsetting other children! He has a good sense of humour and loves to play with my partner, me and my mum but won't interact with anyone else apart from my neice and nephew who he adores but doesn't see very often (they're 11 and 10). He also developed a fear of my hairdryer and has always been scared of the hoover and will cry if they are put on. Some people tell me its a phase but others worry me that it something more like autism and I am scared. I have contact the Health visitor to come and see him. Please can anyone help by telling me they are going through the same thing and more importantly anyone who has been through it and their child has got better. I am so stressed it is not helping him.
