my 17 month old ds has always been a placid happy little chap - until a few weeks ago! he has started to have daily tantrums, throwing his food and drink on the floor at lunch and supper, and having full blown screaming fits - he doesnt seem to know what he wants, and cannot be distracted. I have to wait for it to blow over, which can take 20-40 mins, and then he will let me cuddle him. before this, he pushes me away. I am finding it very hard to cope with, especially since he has a full-on 3 yr old brother, who he no doubt copies! help please!
