No answers but lots of sympathy!! My 10mo DS sounds EXACTLY the same!! I was just on the phoneto my mum today saying that it seems like terrible twos have come early! DS also screams and hits/kicks his toys for no apparent reason, often after just 5-10 mins of playing. He hasn;t bitten yet but does lash out and kick/hit.
He seems to need/want me to play with him almost constantly and is not very good at entertaining himself.
I am finding it v v difficult cos I also have a very firey/short temper and am finding it hard not to get v cross with him in return :( Even though I know he's only youg it's v trying having to cope with all this rage all day every day!
I have started to walk away and ignore him for a few mins when he has a real strop, after trying to distract him with another toy has failed: i think he was starting to learn that this behaviour led to being swept up in mummy's arms and kissed and cuddled, which I don't think is a good association. As long as he is somewhere safe, I just now say in a bored voice "oh dear don't get cross with your toys it's a bit silly" and he normally distracts himself within about 20 seconds. Then when he is calm again I make sure I leave any chores etc and go and play with him on the floor for 15 mins or so....ie so I am 'rewarding' good calm quiet behaviour with lots of fun playtime.
not sure if it's working or not yet but I certainly feel better now I am mentally distancing myself from his strops a bit...I think I needed to realise that I cannot make him happy all the time. I play with him lots, cuddle him loads, take him swimming, out ot baby groups, read loads of books etc: I am trying to be a good mum: but I am not wholly responsible for his happiness all the time: he is a separate person to me, and sometimes he is just going to be annoyed!
I am rambling now and not sure I making any sense, but hope it helpsa bit to know you're not the only one!
A lot have people have told me it'sa sure sign that DS is bright, but I have seen no especial evidence of this so far! Think he is just a bit of a grump!
(my DS cannot walk yet though and I think some of it is frustration...maybe once they can talk things will be better??)
