I have a really irritable 19 mth ds. Although he can be a happy smiley little boy he will always have a few episodes of extreme grumpyness during a day. If he is not interested in a toy someone gives him, he will whack it out the way and grump, he can't bear sitting in car unless moving, and we have given up on taking him to supermarket as he will scream the place down from start to finish in the trolley. If we try to gently direct him in the right direction he will refuse and scream. He often makes it obvious he wants to be picked up but then just is very irritable (ie whinges, bangs his fists against you, arches and thrashes to get down). I often feel like I just have no idea what he wants or how to make him happy, it can be quite depressing. He has always been a bit of whinger (noticeably more than my eldest and he was not easy either) but I think over last few months he has become more irritable and I'm starting to wonder if I should take him to the doctors. Has anyone else experienced this with a toddler?
