He had the jab yesterday and has been really suffering since. He's been crying virtually non stop all evening, he never cries unless hungry. He's barely slept more than 2 hours at a time thru the night when he usually sleeps at least 5 hours. He's not himself at all. Very unhappy, very squirmy and restless - how long will this last?! He's had 2 doses of calpol which really helped so he's clearly uncomfortable :o( but when it wears off he back to suffering again
